kpovmodler in kdegraphics error

I am trying to build kdegraphics from cvs (KDE_3_1_BRANCH) on FreeBSD 
5.0. When building kpovmodler, it quits on this error:

.libs/pmimagemap.o(.data+0x0): multiple definition of `bitmapFileDefault'
.libs/pmmaterialmap.o(.data+0x0): first defined here
.libs/pmbumpmap.o(.data+0x0): multiple definition of `bitmapFileDefault'
.libs/pmmaterialmap.o(.data+0x0): first defined here
gmake[3]: *** [libkpovmodelerpart.la.closure] Error 1
gmake[3]: Leaving directory `/usr/src/kde/kdegraphics/kpovmodeler'
gmake[2]: *** [all-recursive] Error 1

gmake[1]: *** [all-recursive] Error 1
gmake[1]: Leaving directory `/usr/src/kde/kdegraphics'
gmake: *** [all] Error 2

I tried going through the source and fixing it myself, but it was beyond 
me.
