I am on openSuse 11.2 but have the same problem

I had an other problem described in an other thread here
so I set the compilerInstall=System (line 98 in file /.../OpenFOAM-1.6/etc/settings.sh) based on recommendation by grig
after that foamInstallationTest gives the error you have

so you could try to set compilerInstall=OpenFOAM and try whether foamInstallationTest and any application that uses gcc (kde, gnuplot) can run as well

Sir, I have made changes as proposed by you in two file
/OpenFOAM-1.6/etc/setting.sh
as well as
/OpenFOAM-1.6/etc/setting.csh
