The version issue was that the old code generator made use of a rather nasty Perl script (commonly known as the Evil Mangler) to peephole optimize gas output for the STG, and that script breaks on Perl > 5.8.x. In recent GHC versions, this code generator (-fvia-C) is strongly deprecated but still present; it is likely to be removed in GHC 7.2. In short, it would be best to leave it dependent on perl5.8 for people who need to use -fvia-C. - -- brandon s. allbery [linux,solaris,freebsd,perl] [email protected] system administrator [openafs,heimdal,too many hats] kf8nh --------------------------- Would this not be better dealt with by having a +viac (or whatever name) variant that causes the port to depend on perl5.8? It'd be something like variant viac requires perl-5.8 { depends-append port:perl-5.8 } in the ghc portfile, wouldn't it?
