Hi guys,

Dot is installed as part of math/graphviz. It's used to make flowcharts.

When I try it on a certain project that requires it, many instances of the
same error pop up:

dot:/usr/local/lib/libgthread-2.0.so.1803.0: undefined symbol \
'pthread_mutex_trylock'
lazy binding failed!
Segmentation fault (core dumped)
Problems running dot: exit code=139, command='dot', \
arguments='"structupdate__box__coll__graph.dot" -Tpng -o \
"structupdate__box__coll_graph.png"'

This looks extremely similar to an error brought up recently on the list:
http://marc.info/?l=openbsd-ports&m=127238426613149&w=2

You can reproduce it as follows:
- install devel/gmake, devel/doxygen, math/graphviz
- download+extract

- gmake docs

Any info would be appreciated.
