Comment:
There may be no guarantee that different version have the same
executables, but the attached script works perfectly fine for me as long
as the symlinks in /usr/bin point to the the appropriate location in
Current and Current points to one of the versions. For example:
{{{
$ ll /usr/bin/ghc
lrwxr-xr-x 1 62B 26 Oct 17:40 /usr/bin/ghc@ ->
/Library/Frameworks/GHC.framework/Versions/Current/usr/bin/ghc
}}}
{{{
$ ll /Library/Frameworks/GHC.framework/Versions/Current
lrwxr-xr-x 1 55B 8 Nov 19:11
/Library/Frameworks/GHC.framework/Versions/Current@ ->
/Library/Frameworks/GHC.framework/Versions/7.2.1
}}}
