What is 'current Fedora'? glibc 2.14 postdates the current release, Fedora 15, which uses 2.13. I do not know what Fedora 16 will use in several months ....

The main problem will be that the xdr included in R is only for platforms with 32-bit longs -- but that may be true for your i686 Linux. It needs _X86_ defined to compile for i686: I would have expected that to be true on your platform, but am testing a cleaned-up version. If that works it will appear in R-patched within 24 hours.
