Usually Perl gives me nice and helpful error messages. On my new Mini it's not. I
installed newer Perl than Apple currently provide using perlbrew and have my shebang line:
#!/Users/justin/perl5/perlbrew/perls/perl-5.16.2/bin/perl
My perl programs report helpful debug messages at the command line, but when I hit Cmd+r
to have TM run the program they look like this:
BEGIN not safe after errors--compilation aborted at
/Users/justin/perl5/perlbrew/perls/perl-5.16.2/lib/5.16.2/Carp/Heavy.pm line 3.
Compilation failed in require at
/Applications/TextMate.app/Contents/SharedSupport/Bundles/Perl.tmbundle/Support/exception_handler.pm
line 30.
My TM_PERL variable is also:
/Users/justin/perl5/perlbrew/perls/perl-5.16.2/bin/perl
Reading through the exception_handler.pm file I see that line 30 is 'require
Carp::Heavy…'. When I tried to install Carp/Heavy.pm using cpan it said that the
module is up to date.
Any suggestions on what's not right here?

Does running this (in a terminal) work:
/Users/justin/perl5/perlbrew/perls/perl-5.16.2/bin/perl -e 'require
Carp::Heavy'
If not, you likely tried to install the module for the system default perl, but you need
to install it for the version of perl that you installed via homebrew.

That command runs without error (I did a copy and paste to ensure no typos). To check it I
replaced Carp::Heavy with Lies::DamnLies and got the expected error.
I forgot to mention this is TM 1.5.11 (1635).
I've looked at this some more and can't see what might be wrong.

Hi Justin and Allan,
that error message rings some distant bells for me: maybe it's related
to Perl's taint mode? Why would we be seeing a taint-related problem
after changing the binary that "perl" points to? Perhaps because the
file "perlcheckmate.pl" in the Perl bundle's support folder has a
slightly mysterious shell-out to perl with -T turned on: line 33 of
that file reads
my @lines = `perl -Tcw "$file" 2>&1`;
I'm guessing that if your path to the new perl may not be secure, or
something like that --as per taint's requirements-- that message
you're seeing might come flying out the other end. See "perldoc
perlsec" for what triggers taint mode.
Anyway, easy to check if I'm blowing my usual volume of hot air here:
just remove the taint check (ie the "T" in the line quoted) and see if
the error still appears. Then you can start the hunt in earnest!
Good luck,
Paul

Thanks for the pointer, Paul. Unfortunately that doesn't seem to be the solution. I
removed the "T", opened a script, ran it to check it worked and that was fine,
but if I introduced an error I got the same "exception_handler.pm" error, and
not the usual useful Perl error messages.
I might try a perl newsgroup.

Hi Justin,
I don't know if you have solved your issue already, but here there's a
viable workaround:
/add a "use Carp::Heavy;" statement to your scripts./
I've been having this problem myself since forever, and the workaround
solved the issue for me.
Still I don't have a sound technical explanation of HWY this happens, nor a
cleaner solution.
I found this workaround here
<http://textmate.1073791.n5.nabble.com/TextMate-perl-bundle-issues-td14163.html>
.
Please let me know if you find a better solution!
Kind regards,
Giovanni
