Compiling Wings3D in OSX

[dgud]

Hmm, it seems you have done something wrong with ERL_LIBS
Basically(*) the compiler should be able to find the include file with the absolute path:
$ERL_LIBS/cl/include/cl.hrl

* ERL_LIBS might contain several directories which the compiler will try and the application
directory name may contain version number, i.e. cl-1.12/include/cl.hrl which the compiler will expand.

If you want to help out with the UI I have remade most of it on my wx-backend branch on github
so I don't want any patches on the old UI just now, I expect/hope to release the new wx-backend
before summer.

In the new branch I have changed (or will change) the icons to be PNG with alpha instead BMP with hard coded background colors.
