Hi,
after svn updating all my *.tmbundle, including the latex bundle, after running a previously working latex-project, I got after cmd-R:

/tmp/temp_textmate.hXj0XQ:3:in `require': no such file to load -- /Applications/TextMate.app/Contents/SharedSupport/Support/lib/tm/process (LoadError) from /tmp/temp_textmate.hXj0XQ:3

I looked around, and found that likely I have to also svn up the "Support Folder":
cd /Library/Application\ Support/TextMate
svn co http://macromates.com/svn/Bundles/trunk/Support

so I did, however, when I run
echo "$TM_SUPPORT_PATH"
I get
/Users/clausman/Library/Application Support/TextMate/Support
and not
/Library/Application Support/TextMate/Support
as I should according to
http://manual.macromates.com/en/bundles

Now, at first this didn't bother me too much,
but when I tried to cmd-R on my latex project, I got
Error: Could not open to check for packages
This is most likely a problem with TM_LATEX_MASTER

(I have TM_LATEX_MASTER set under cmd-I)
interestingly, this error even occurs when I try to compile a single, basic latex file like the following four lines (and I thought TM_LATEX_MASTER is only necessary when using projects?)
\documentclass[article]
\begin{document}
Hello World
\end{document}

Can anybody help me how to get latex running again?
Is the "$TM_SUPPORT_PATH" the problem?
Or is there anything major different in the latex bundle recently (last half year or so)?

Thanks for your help,
Claus
