interpolation library

Dear GRASS programmers,

Compiling an interpolation library developed by Irina Kosinovsky
and Helena Mitasova I got some errors. It seems to be a specifically
IBM RS/6000 (which I use) problem. A compilation in data, tree and
interp was without any problem, however it failed in r.resample.tps,
s.surf.tps and v.surf.tps. I would appreciate any help.
Thank you very much in advance.
