glew-1.6.0 breaks pymol

[howarth@…]

The update to flew 1.6.0 breaks pymol which now depends on it. After updating glew to 1.6.0, the pre-existing pymol package fails with the error...

The trivial fix is to force pymol to be rebuilt with a revision bump...

however the glew package also seems flawed. The installed libraries have no settings for the compatibility and current versions on the shared library...

	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.0.0)

Also it is unclear if we should be installing a libGLEW.1.6.dylib only or also a libGLEW.1.dylib to have everything using glew linked to libGLEW.1.dylib and ease the transition to future 1.x releases. Fink takes this approach with...

[MacPro:/opt/local/lib] root# otool -L libGLEW.1.6.0.dylib
libGLEW.1.6.0.dylib:

/opt/local/lib/libGLEW.1.dylib (compatibility version 1.6.0, current version 1.6.0)
/System/Library/Frameworks/AGL.framework/Versions/A/AGL (compatibility version 1.0.0, current version 1.0.0)

/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.0.0)

so that the installed named for libGLEW.1.6.0.dylib is actually /opt/local/lib/libGLEW.1.dylib. An explicit creation of the /opt/local/lib/libGLEW.1.6.dylib symlink is added to the Portfile.

Rev bumped in r78272. I think the versioning issue should be raised upstream.
