Ah, sorry for the noise. You are indeed right. NetBSD ships with a  
libpixman-1 in /usr/X11R7/lib, which does not export the problematic  
symbols.

After quite a bit of testing, I finally found out that the problem is  
the -R/usr/X11R7/lib flag on the command line (copied below for  
reference). This option is understood by NetBSD's gcc and it ends up  
as an *initial* -R flag to the linker, whereas the -Wl,-R<dir> options  
stay in their place. That means that the broken libpixman will be  
found before the right one in /usr/pkg/lib. Unfortunately, the -R flag  
is added automatically by autoconf when testing for the X libraries,  
so we cannot get rid of it. A workaround is to invoke configure as
  ./configure LDFLAGS=-R/usr/pkg/lib

I also noticed that configure.ac contains some code to add some  
additional target OS directories to CPPFLAGS and LDFLAGS. In  
particular on NetBSD it uses LDFLAGS="$LDFLAGS -Wl,-R/usr/pkg/lib -L/ 
usr/pkg/lib". I expected that changing -Wl,-R/usr/pkg/lib into -R/usr/ 
pkg/lib would allow invoking configure without the extra arg; but for  
some reason this didn't work (maybe it was just late at night  
yesterday).
