Tedious Mac question

[fivemack]

Tiger seems to have broken ghci, which now says


Tom-Womacks-Computer:~/Projects/haskell tom$ ghci

dyld: Library not loaded: /sw/lib/libncurses.5.dylib

Referenced from: /sw/lib/libreadline.4.dylib

Reason: Incompatible library version: libreadline.4.dylib requires version 6.0.0 or later, but libncurses.5.dylib provides version 5.0.0

Trace/BPT trap

This is a very specific question but must be a case of a general problem; can anyone help me out?

I take it updating fink doesn't help? IIRC everything under /sw is fink, so it looks like they're mismatched rather than Tiger per se...

fink update-all tells me there's nothing to update

fink update readline tells me that it can't compile readline-4.3 with gcc-4.0 (whose changed ABI may be the cause of all this fuss in the first place)

I'd recompile ghc from source, except that the source is in Haskell with ghc extensions!

An example of why Wirthian self-hosting compilers are, while theoretically wonderful and pure and neat, in practice more pain than they're worth ;)

I didn't realise gcc 4 had changed the ABI yet again, I thought that'd been locked down early in the 3.x cycle. Bah.

You can bootstrap from .hc files. But I doubt it's a pleasant process.

#haskell thinks that this is a known problem that will hopefully be fixed soon. Not quite sure where to keep an eye on for the fix, though.
