It appears that your flex in /usr/local/bin is not being found.
It is possible that PATH for the build environment does not 
contain /usr/local/bin probably in order to have a controlled
build environment.

Why don't  you temporarily do:

ln -s /usr/local/bin/flex /usr/bin/flex

and see if that works.
