Which version of OS X are you using?

I have had these messages intermittently for quite some time now.
Hans Jörg Bibiko, author of the R bundle, has not been able to find a cause.

The error message means (quoting from email from Bibiko):
The error "Invalid argument (Errno::EINVAL)" is related to an issue that something couldn't be read or written to a file handle (incl. pipes).

It may be possible that the ruby  script has to wait too long  for the io pipe to deliver something (I'm guessing)

It would certainly be interesting to hear f more R and TextMate users are experiencing this issue.
