Hi I am running under linux suse kernel 2.4.x What I did was just install the rpm from suse for the package f2c which contains that libray object. Check the Debian distribution on this package

Check on your system under the path where mod binaries are

ldd -d mod_xxx

Anyway even after a suscesfull linking of that objects to produce the binary for modeller I have an error that I reported to Dr Sali and I am awaiting for his reply
