Compile Grig-0.7.1

Hi All....Tnx for reading this.....
I have just installed Hamlib-1.2.5 from tarball on my Mandriva Linux 2006 system.....works ok with most programs wanting Hamlib...
However i am trying to compile Grig-0.7.1 and when i go ./configure it says Hamlib 1.2.5 is not installed.....the README
in the Grig tarball says that the devel file which has the headers is needed....have scoured the net but cant find a Hamlib-devel file for 1.2.5...there was for Hamlib-1.2.4..... Does anyone know how to overcome the compile problem with Grig-0.7.1 and and where it looks for Hamlib-1.2.5....
Ive also looked for any forums or mail on this subject but cant seem to find any....

Tnx for your help
