Quick summary: I missed the file ~/.MacOSX/environment.plist This file is used by GUI applications (like TextMate) to find the path to command line commands, e.g. TeX commands etc
Can't this also be fixed by uncommenting . "$TM_SUPPORT_PATH/lib/ bash_init.sh" in LatexCiteCompletions.sh? It seemed to work on my system (I prefer not to edit environment.plist).
Does not work here. I moved the environment.plist file and uncommented $TM_SUPPORT_PATH/lib/bash_init.sh in LatexCiteCompletions.sh, and I get the same error as before. Adam: maybe you have an environment.plist file after all?
