graphviz: stuck with "Undefined symbol" problem

[Andrea Venturoli]

Hello.
Running doxygen from a makefile I get a lot of messages like the
following ones:

/libexec/ld-elf.so.1: /usr/local/lib/graphviz/libgvplugin_gd.so.4:
Undefined symbol "gd_alternate_fontlist"
Problems running dot: exit code=1, command='dot',
arguments='"xxx__incl.dot" -Tpng -o "xxx__incl.png"'

Now:
# which dot
/usr/local/bin/dot
# pkg_which /usr/local/bin/dot
graphviz-2.14.1
# pkg_which /usr/local/lib/graphviz/libgvplugin_gd.so.4
graphviz-2.14.1


I did a "portupgrade -RNf graphviz", but I still experience the same
problem.
On another box the same procedure runs fine.

Any hint?

  bye & Thanks
