[Bug-gnubg] error building latest src

[w bugar]

Hi, I tried
rpmbuild --recompile gnubg-0.15-4.src.rpm
and got the following errors (did I do something wrong?):

/bin/sh ../libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I..     
-g -O2 -MT neuralnetsse.lo -MD -MP -MF .deps/neuralnetsse.Tpo -c -o 
neuralnetsse.lo neuralnetsse.c
 gcc -DHAVE_CONFIG_H -I. -I.. -g -O2 -MT neuralnetsse.lo -MD -MP -MF 
.deps/neuralnetsse.Tpo -c neuralnetsse.c -o neuralnetsse.o
