the gist of this issue is that "parsec >= 3.0 || == 2.1.*" is translated to
"parsec>=3.0", which is just plain wrong. Now, wouldn't it be easiest to
modify cabal2arch so that it translates that specification to "parsec>=2.1"?
A straight-forward algorithm to accomplish that would be to use the *lowest*
version bound in these kinds of alternatives. Right now, cabal2arch appears
to be using the *first* version bound, which is not exactly optimal.

Am I missing something?

Take care,
Peter
