Hi,
I'm trying to build g19d and get an error when doing "make"

make  all-recursive
make[1]: Betrete Verzeichnis '/home/janolehuebner/g19/g19d'
Making all in src
make[2]: Betrete Verzeichnis '/home/janolehuebner/g19/g19d/src'
/bin/bash ../libtool  --tag=CC   --mode=link gcc  -g -O2 -rdynamic -ldl -lg19 -lg19draw  -o g19d g19config.o g19screen.o g19dutil.o g19plugin.o g19d.o   -lfreetype

sorry for the german console parts but it should be understandable.

I have no idea what to do here.
Thanks for the help
