If you have doxygen (and eventually graphviz) the pkg-plist
is incorrect.
If you want install the documentation, you have to install
doxygen.
If you want generate inheritance diagrams to the documentation
to have to install graphviz.

Fix: I use this patch:

For multimedia/dirac/Makefile:

For multimedia/dirac/pkg-plist:

And a new multimedia/dirac/files/patch-configure:



pre-install:
	${MKDIR} ${DOCSDIR}/programmers

because the installation process break when the istall.sh create
the programmers directory. This problem is documented in the
wrk/dirac-0.5.0/install.sh--yf8FZLFBRDtu1AC8fjWKryoAT1f7QTvS9JrGNPgCzNpjCq0z

How-To-Repeat: Install doxygen (and eventually graphviz). The configure test find
the doxygen command (and eventually the dot command) and install
the documentation (with graphics generated by dot).
