 I got weird behavior with `opencascade`. First of all, it tries to pull
 symbols for system frameworks from MacPorts prefix:
 {{{
 36-25% /opt/local/libexec/opencascade/bin/draw.sh
 Hint: use "pload ALL" command to load standard commands
 dyld: Symbol not found: __cg_jpeg_resync_to_restart
   Referenced from:

   Expected in: /opt/local/lib/libJPEG.dylib

 /opt/local/libexec/opencascade/bin/draw.sh: line 10: 50815 Trace/BPT trap
 DRAWEXE

 dyld: Library not loaded: /opt/local/lib/libjpeg.8.dylib
   Referenced from: /opt/local/lib/libTIFF.dylib
   Reason: image not found

 trap          DRAWEXE

 dyld: Symbol not found: _gll_noop
   Referenced from:

   Expected in: /opt/local/lib/libGL.dylib

 /opt/local/libexec/opencascade/bin/draw.sh: line 10: 50968 Trace/BPT trap
 DRAWEXE
 }}}

 This is not linking, it just seems to shade away system libs even for
 system components.

 I have to deactivate `libjpeg-turbo`, `tiff`, `giflib`, `mesa` and
 `libGLU`.
 Once that is done, no more symbols errors, but the app crashes when I try
 to do something in it.
 {{{

     Original error:

 }}}

 (Initially there is a malloc error too, but that I have fixed via adding a
 path in the wrapper.)

 Crash aside, such behavior with libraries I see for the first time, I
 think.
