I've been struggling with a program under Linux emulation for a couple of
days now, and I'm beginning to suspect some sort of problem as a result of
multiple-upgrade-induced-cruft. Hopefully someone can either refute my
theory or point out where my problem might lie.

The situation, briefly, is this: I have two machines, both running 3.3. One
is a fresh install from a week ago, the other a box I've had since 2.9 and
upgraded manually each time. On the fresh box, I installed redhat_base from
ports (which was version 6.2p7), downloaded my program -- the FoldingHome
distributed computing client -- ran "elf2olf -o linux" against it, and had
it up and running in a flash. The only caveat I ran into was that this
program uses multiple cores, which are in and of themselves binaries, which
I just borrowed from a Linux box I've got, elf2olf'd, and ran.

On the older system, I repeated the steps above, with the execption that I
had redhat_base version 6.2p5 running already. It seemed to work, but it
never made any progress, which told me *something* was running differently.
At this point, I updated my ports tree, only to see redhat_base 6.2p6; to
ensure a properly parallel environment, I made a package of 6.2p7 on the
functional box, moved it over, pkg_delete'd 6.2p5 from the older box, and
pkg_add'ed 6.2p7 there. Much to my surprise, the program still behaved the
same.

I'm working with the FoldingHome people to find a solution to this, but
after everything I've tried on that end, I was hoping that someone here
might be able to point to a possible Linux emulation issue or a flaw in my
methodology above. Alternately, if anyone out there is interested in this
particular distributed computing project and can try this out on their box
(either with existing or fresh Linux emulation), your results would probably
be *highly* helpful in debugging my problem. Again, for those who might be
interested, I'll be posting a HOWTO/FAQ of how to get FoldingHome running
under OpenBSD on my web site (URL to follow if I'm successful) once I have
this working consistently.

I appreciate any assistance anyone can provide on this.

Thanks,
Alex Kirk
