Hi Frederik,
csh: FDK.init: No such file or directory. /bin/bash: line 2: : command not found
I think the problem is probably that you have something funny in your ~/.cshrc file. The error manifests, because older versions of the run command were using the `which` (which happens to be written for csh) command to find python.
Try finding out what's wrong with your .cshrc or just get rid of it entirely. Previously, people have had incorrectly quoted environment variables. So maybe that is the case.
Alternatively, you can switch your TextMate to "Cutting-Edge" updates, to get a more recent version of the Python bundle that no longer uses `which`.
Another possibility is that you have some outdated version of the bundle in ~/Library/Application Support/TextMate/Bundles/ that is overriding the version distributed with TextMate in which case you should remove it.
Did this help?
