  Awhile ago, I had an experience departing from pkgsrc-perl's
default threading disposition in which there was significant, un-
expected rebuild-cascade-effect.  I was using mod_perl (and apache
1.x), so I had to try to re-build it with threading that matched
perl's; and, accordinly, to try to rebuild apache itself--and all
its other modules--that way, too.

  Some package in the chain wouldn't work (maybe there were build
errors I couldn't fix or maybe it just plain didn't offer any
threading options, and wouldn't fit with the rest of the chain).
Anyway, I had to go back and rebuild everything all over again,
starting with perl itself, using the default threading disposition.

  If you use mod_perl now, everything might be ok (especially maybe
w/apache2?).  Suffice it to say though, soon after the above was
when I started "caching" my pkgsrc builds into binary packages (via

    make update UPDATE_TARGET=bin-install BINPKG_SITES=

) so I could back out of rebuild snafus more easily...
