OSX 10.11 El Capitan can't run LaTeX extension

[Julian Gilbey]

The OSX Inkscape launcher, in packaging/macosx/Resources/bin/inkscape in the bazaar repository, sets up the PATH environment variable to ensure that LaTeX is found (needed for the Render -> LaTeX formula extension). However, on OSX 10.11 (El Capitan), the /usr/texbin symlink is no longer present, and /Library/TeX/texbin is used instead.

Trivial patch to fix this bug:

In line 46 of this file, prepend the extra path component /Library/TeX/texbin. (Don't remove the existing one, as older systems still use /usr/texbin; some systems have both symlinks present.)

To bypass Gatekeeper, please follow these steps [2]:
1. From System Preferences, open "Security & Privacy".
2. At the bottom of the General pane, change "Allow apps downloaded from:" to "Anywhere".
3. Start Inkscape.
4. After Inkscape has launched, go back to "Security & Privacy" and revert the setting to "Mac App Store and identified developers".

Please note that this is not an official stable package (there has been no bug-fix release of the stable release branch yet) - if you report bugs against this build, please mention details (DMG name, Inkscape version (menu 'Help > About Inkscape'), OS X version) in the bug description, thank you.

[2] The application is not signed, and bypassing Gatekeeper on a per-app basis no longer seems to work for Inkscape.app after security updates provided by Apple earlier this year (bug #1478053)
