attempting to install rJava on R-2.7.0, x86_64 platform, config.log shows the
following error:
configure:3880: checking whether JNI programs can be compiled
configure:3898: gcc -m64 -std=gnu99 -o conftest -g -O2

It looks like the command above could use /lib64/libc.so.6, but running "R CMD
javareconf" shows that JNI linker flags don't contain any entry similar to
'-L/lib64':

Suggests on the root of the problem or best workarounds?
