I have seen an earlier post with gcc errors, however I couldn't figure out what the actual problem here is: is it that libmpfr.so.4 is not found? or gcc needs to be installed fresh?
libmpfr. Unless I've misunderstood, the other errors are simply configure trying to work out which compiler you're running - -V and -qversion simply aren't valid flags to gcc - so those "error" lines are expected result.
