[Eric] Eric5 at Mac OS X / Homebrew

[Hirschfeld Michael]

Hi Detlev,

unfortunateley 'prefix' is no environment variable which can be tested via os.environ.

It's more like an variable for the install dir, set by the package manager Homebrew via the formula and which puts normaly a "usr/local/Cellar/PackageName/Version/"  before the softwares install path. 
Example for Homebrews directory structure: http://img4.picload.org/image/lolagaa/09_04_14_22_09.jpg

So for instance some files of eric5 landed in "/usr/local/Cellar/python3/3.4.0_1/Frameworks/Python.framework/Versions/3.4/lib/python3.4//site-packages" which is a symlink to "/usr/local/lib/python3.4/site-packages"

Maybe these links can explain it a bit better: https://github.com/Homebrew/homebrew/wiki/Homebrew-and-Python andhttps://github.com/Homebrew/homebrew/wiki/Gems,-Eggs-and-Perl-Modules

Somehow this doesn't work with the macAppBundle. A  Homebrew dev suggested it is because of a hardcoded path in install.py.
