gplc libraries not found

[Dr LLSJ Krüger PrEng]

    I decided to try the examples that comes with the source, but I get
    stuck:
    
    gplc --fast-math
        --min-bips -o boyer boyer.pl
      
      cannot locate file libbips_fd.a
      
    How do one ensure that the compiler find the libraries? I
    have them in /usr/lib64.  I can't find a setting to tell the
    compiler where to look.
    
    Regards.
