I have found the problem, it's zlib. In r206708-9 delphij updated zlib
to version 1.2.4.3 and did some magic with the symbols. I just regressed
my system to r206707 and now the same vlc does xvid just fine.
When I booted the new -current yesterday (after the libz changes) I had
to rebuild and reinstall openbox and libxml2 because the latter had some
sort of unresolved symbol problem related to libz. When I regressed the
system today and had to do the same thing I got this error:
/usr/local/lib/libxml2.so: undefined reference to `gzo...@zlib_1.2.4.0'
(Note, this libxml2 that generated this error was compiled against the
NEW libz, so it's not the error that I was seeing previously.)
In looking over the things in /usr/lib that may be related I see that
gpac-libgpac-0.4.5_4,1 has the gzopen symbol, and I did not recompile
that when I was trying to get vlc to work last night so it may be the
magic bullet.
My plan at this point is to re-upgrade to the latest -current, record
the error I get from libxml2 when recompiling openbox, and then try
recompiling stuff until I find the one that does the trick. Worst case
scenario I do 'portmaster -f vlc' but that constitutes 175 ports, which
would take a while.
