Comment(by Mikolaj):
Thank you. The problems with black hole are gone. I've recompiled Debian's
ghc6_6.12.1-13 after applying your change, and the parallel tests now are:
{{{
3 total tests, which gave rise to
19 test cases, of which
0 caused framework failures
15 were skipped
4 expected passes
0 expected failures
0 unexpected passes
0 unexpected failures
}}}
where the skipped tests are unrelated to black hole and probably due to
the Ghostscript problem, as in the previously attached log.

That's probably powerpc (Linux) specific (I know, I know), but perhaps
somebody has an easy fix... I guess it's a problem with GHC (6.12.1,
recompiled from source, to be sure), not the 'parallel' library.
The bug is a failing test suite for
http://hackage.haskell.org/package/parallel, versions from 1.1.0.1 to at
least 2.2.0.1. Version 1.1.0.0 works fine and the culprit is the following
clause in parallel.cabal:
{{{
if impl(ghc = 6.11) {
-- To improve parallel performance:
ghc-options: -feager-blackholing
}
}}}
Some relevant lines from the test output:
{{{
= conc057(threaded2)
cd . '/home/mikolaj/Desktop/ghc6-6.12.1/inplace/bin/ghc-stage2'
-fforce-recomp -dcore-lint -dcmm-lint -no-user-package-conf -dno-debug-
output -o conc057 conc057.hs -O -threaded -eventlog -O0 -package parallel
conc057.comp.stderr 21
Compile failed (status 256) errors were:
/usr/local/lib/parallel-2.2.0.1/ghc-6.12.1/libHSparallel-2.2.0.1.a(Strategies.o):
In function `sXK_info':
(.text+0x56): undefined reference to `__stg_EAGER_BLACKHOLE_INFO'
/usr/local/lib/parallel-2.2.0.1/ghc-6.12.1/libHSparallel-2.2.0.1.a(Strategies.o):
In function `sXK_info':
(.text+0x5a): undefined reference to `__stg_EAGER_BLACKHOLE_INFO'
}}}
I attach the full test output from version 2.2.0.1 of parallel and a
similar compilation failure, when using parallel 1.1.0.1 in vty in
LambdaHack.
