Hi!

After i failed compiling gprolog i gave swiprolog a try. One of its  
dependancies, however, failed to build:

Any idea, what i can do? This looks like a missing lib or a missing  
path for the linker, but i'm not really familiar with pkgsrc- 
internals so i don't know how to fix this.

Thanks,
