Because the ports seem not to get updated, I tried to compile ghc 6.10.1 under freebsd 7 on amd64 myself. For compiling I first used the ports ghc The tree's not being updated because 64-bit on freebsd doesn't work yet, as you found. I believe a fix for the mmap() problem has been committed for the upcoming 6.10.2. Yes.

The patches haven't been merged into stable yet, but you can grab a HEAD snapshot and try that instead - we'd appreciate the testing.
I checked out and translated the head version of ghc today from darcs. It compiled fine. When I now try to start the ghci I get the following:
---- snip ---- GHCi, version 6.11.20081126: http://www.haskell.org/ghc/ :? for help ghc: internal error: loadObj: failed to mmap() memory below 2Gb; asked for 626688 bytes at 0x40000000, got 0x801635000.

If it helps somehow, you can find the core dump here: http://www.alios.org/~alios/ghc.core.bz2
That's odd, because 6.8.3 is using 0x40000000 on FreeBSD and is working fine (or is it?). Ideally I need to find out what the memory map is for GHCi. I posted some instructions for doing this on Linux/Xen, maybe you can adapt these to work on FreeBSD: http://www.haskell.org/pipermail/glasgow-haskell-users/2008-November/016091.... The bit that needs to change is 'cat /proc/<pid>/maps' - does FreeBSD have something similar? Also you could try doing as the error message suggests, and specify a different address. e.g. ghci +RTS -xm30000000 ghci +RTS -xm50000000 for 0.75 and 1.25GB respectively. Cheers, Simon
