New description:
I've seen this a handful of times since the new build system was pushed.
I'm using exclusively x86_64 systems. The error message is
{{{
/usr/bin/ld: cannot find libraries/base/dist-
install/build/GHC/Enum_split/Enum__1.p_o
}}}
Turning on make's debug information makes it clear that some process, I
presume split,
is not completing before linking occurs.
Simply restarting the make completes the build most times (I think only
once has
a second error occurred and I'm not 100% that I had made no
modifications).
This happens on a dual-core debian system and an 8-core RHEL5.3 or
Fedora-11 system.
If you need make's debug output send email to gbeshers at gmail dot com,
but I am
hoping just adding a dependency will work.
