5580	Make switching GHC versions easier on Mac OS	pumpkin		"The standard .pkg installer for GHC or the platform follow the Mac OS convention of keeping different versions in separate version folders in the framework, with a symlink from Current to the current version. However, the wrapper scripts (/usr/bin/ghc, runhaskell, ghci) all explicitly mention the full path to the GHC that was most recently installed, like

{{{
datadir=""/Library/Frameworks/GHC.framework/Versions/7.3.20111017-x86_64/usr/share""
}}}

This prevents us from easily switching versions by just changing the symlink to an older version. Could the variables in the GHC script be changed to something like

{{{
datadir=""/Library/Frameworks/GHC.framework/Versions/Current/usr/share""
}}}

so we can switch more easily?"	feature request	closed	normal		Compiler	7.2.1	wontfix		leather@…	Unknown/Multiple	Unknown/Multiple	None/Unknown
