Found this fix for my error:
To check if you previously installed the library in your machine run the command on your terminal
I was looking for libxaw so i searched for "Xaw"
$ find /opt/X11/ -name "*Xaw*"
you should see an output of the search mine showed that i had libxaw7 which is what i was searching for

If not you can use homebrew to download the libraries
https://github.com/Homebrew/homebrew-x11
or you can just install xQuartz from
https://www.xquartz.org/
I was still getting the error then i realized that i needed to pass the flags
export CFLAGS=-I/opt/X11/include && export LDFLAGS=-L/opt/X11/lib
learned that the toolchain won't find x11 in /opt
from this post.
Mountain Lion X11 libraries can't ./configure
