The system is FC8

$ file /usr/bin/gcc
/usr/bin/gcc: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), 
dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped

there is no file called ccache (locate finds only the yum headers).

]$ /usr/bin/gcc -v

Is there an easier way to build just a single package?  Is there a 
package for RXTX that already exists (if so I haven't found it).

Thanks,

Jim
