So it turns out that i have gcc34 installed should I do a find and replace
in the generated make file for gcc ->gcc34 I assume there is a better way.
Googleing told me to rm the gcc link and sym link /usr/bin/gcc->gcc34 but
that seems unwise and a bit wrong because the gcc I have in my /usr/bin is
NOT a sym link its the actual executable.
