Unable to build "graphics/netpbm-devel"

[GESBBB]

I am unable to build "usr/ports/graphics/netpbm-devel". The ports tree is up-to-date. The build always fails with this message:

libopt results: ' -L/usr/ports/graphics/netpbm-devel/work/netpbm-10.31/lib -lnetpbm -L/usr/local/lib -ljbig'

I would appreciate any assistance.
