Comment:
I have a tentative solution. Tentative because it did resolve the problem
for me, but I don't know if this would help the similar reported errors.
When I started, I was upgrading from GHC 6.8.3 to GHC 6.10.1, which
created a new ghc-pkg database, so I had then attempted to re-install all
the library packages I had previously installed.
It seems that the problems start occurring when I installed the
unix-2.3.1.0 package. This package is (no longer) necessary for my
environment because the functionality is now builtin to GHC 6.10.1;
actually installing and registring unix-2.3.1.0 introduced the failures
described here.
Another clue was that directory started causing problems:
{{{
[ghc] src/Darcs/Commands/Apply.o
/Programs/GHC/6.10.1/lib/ghc-6.10.1/directory-1.0.0.2/System/Directory.hi
Declaration for removeFile
Unfolding of System.Directory.removeFile:
Can't find interface-file declaration for variable
System.Posix.Files.a52
Probable cause: bug in .hi-boot file, or inconsistent .hi file
Use -ddump-if-trace to get an idea of which file caused the error
}}}
and
{{{
[ghc] darcs
/Programs/GHC/6.10.1/lib/ghc-6.10.1/directory-1.0.0.2/libHSdirectory-1.0.0.2.a(Directory__71.o):(.text+0x29):

...
}}}
I rebuilt and re-installed GHC 6.10.1 and did *not* install unix-2.3.1.0.
I am now successfully able to build darcs.
As a side note, I cannot build QuickCheck-2.1.0.1 with GHC 6.10.1; I don't
know if this is a known issue or not:
{{{

Anyhow, root cause was PEBKAC... sorry to have wasted your time.
