Haven't got RedHat 7.2 available, but your example works perfectly on
SuSE 7.3, Solaris 5.7 and WinXP.
So I guess you didn't compile R (or e1071) on your system. 
Maybe there is a small incompatibility with the precompiled version.
I'd suggest to compile R yourself and install e1071 from the sources.
