Has anyone tried to build trinity for FreeBSD ?

I am currently building a new system based on FreeBSD and I would like 
to attempt to build trinity.

I would like to create ports build if I am successful with the build.

I am studying the build from source instructions posted on the website.  
I believe that this will be a difficult one as it appears that trinity 
favors Linux.

The following appears to be problem areas:

Should be installed in /use/local/<whatever>.

Scripts contained in the source files have !#/bin/bash.
     Do the scripts contain bash-ims?
     FreeBSD used the bourne shell not bash IE #!/bin/sh.

FreeBSD uses clang instead of gcc.

FreeBSD has dropped HAL in xorg.  udev not supported.

I am not intending to use linux compatibility ports, as I am looking to 
run this on the FreeBSD bare metal.

Comments?
