gnuplot compilation problem on 2011Q2

[Anne Bennett <anne%porcupine.montreal.qc.ca@localhost>]

Just a quick note to describe a problem I encountered and worked around...

While compiling gnuplot, it failed with these errors:

    cc  -O2 -I/usr/pkg/include -I/usr/include -I/usr/X11R7/include

I figured out that "-lpixman-1" was missing from the "cc" command
above, so I issued this to compile that one file:

    ( cd /usr/pkgsrc/graphics/gnuplot/work/gnuplot-4.4.3/src && cc  -O2 
-I/usr/pkg/include -I/usr/include -I/usr/X11R7/include 
-I/usr/X11R7/include/freetype2  -L/usr/pkg/lib -L/usr/lib -Wl,-R/usr/lib 
-Wl,-R/usr/pkg/lib -L/usr/X11R7/lib -Wl,-R/usr/X11R7/lib -L/usr/pkg/lib 
-L/usr/X11R7/lib -Wl,-R/usr/pkg/lib -L/usr/pkg/lib -L/usr/pkg/lib 
-L/usr/X11R7/lib -Wl,-R/usr/X11R7/lib -Wl,-R/usr/pkg/lib -pthread 
-L/usr/X11R7/lib -o gnuplot_x11 gplt_x11.o  gpexecute.o getcolor_x11.o 
-L/usr/X11R7/lib -R/usr/X11R7/lib -lX11 -lm  -Wl,-R/usr/pkg/lib -pthread 
-Wl,-R/usr/X11R7/lib -L/usr/pkg/lib -L/usr/X11R7/lib -lpixman-1 
-lpangocairo-1.0 -lcairo -lpangoft2-1.0 -lpango-1.0 -lm -lfreetype -lz 
-lfontconfig -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lglib-2.0 -lintl )


... and was then able to re-issue my usual installation command successfully:

    cd /usr/pkgsrc/graphics/gnuplot && make install && make clean


I have no idea why "-lpixman-1" is missing.  My installation is
quite "vanilla": I had issued "pkg_delete" until everything (2010Q4)
was gone, and am now installing everything from scratch.

I'm also puzzled because the DESCR file for pixman says it's "for
modular X.org", but I'm using the X that came with the system
(tracking branch "netbsd-5").

In any case, the "gnuplot" program that was installed as a result
of the above intevention seems to work correctly, so this is not
an urgent problem from my point of view, but I think something
needs to be tweaked in the gnuplot Makefile.
