>Description:
graphics/transcode (transcode-0.6.9nb1) fails to import audio module.
As a result, programs that depend on transcode (e.g. dvdrip) fail
to work.

It appears that when transcode tries to import the module (e.g.
/usr/pkg/lib/transcode/import_dvd.so) there is undefined symbol
"sigwait". Exctract from transcode output (full output is attached
later):

 loading audio import module /usr/pkg/lib/transcode/import_dvd.so
 [transcode] warning : Undefined symbol "sigwait"
 (decoder.c) loading audio import module failed
 [transcode] failed to init import modules
 [transcode] critical: plug-in initialization failed

The said module should however be able to find the sigwait from
libpthread (in which sigwait should be defined?):

 % ldd /usr/pkg/lib/transcode/import_dvd.so
 /usr/pkg/lib/transcode/import_dvd.so:
          -ldvdread.3 => /usr/pkg/lib/libdvdread.so.3
          -liconv.4 => /usr/pkg/lib/libiconv.so.4
          -lm.0 => /usr/lib/libm387.so.0
          -lm.0 => /usr/lib/libm.so.0
          -lpthread.20 => /usr/pkg/lib/libpthread.so.20
          -lintl.0 => /usr/lib/libintl.so.0


>How-To-Repeat:
1. Install graphics/transcode from pkgsrc.

3. Transcoding DVDs using dvdrip fails because of the same error.
