Did you contact the GHC team for help? They seem to be very supportive.

Did you try starting with this?

I gave up. I just keep the Sparc because...

I take it from that statement that this is somewhat obsolete hardware?

If you gave up and noone else cares enough to do it, is that good reason to condemn GHC?

With respect, your failure to build a compiler on a piece of obsolete hardware, no matter how convenient it may be to you, seems hardly a good reason to condemn the Perl6 VM effort to sticking with C.

Note. I'm not championing GHC--Haskell leaves me cold. I'm simply suggesting that for a new language that has no legacy code to support and therefore has no real need to support legacy platforms, clinging doggedly to C and gcc simply because it is known to be buildable on a 2.4 kHz, steam powered Eniac lookalike doesn't seem sensible.

Unless you want Perl6 and it's VM to paint themselves into a support corner as the Perl 5 sources have done.
