OK so my bug was indeed precipitated, sorry about that =D

The thing is that byoubu is still not working because it isn't in the PATH, here is why:

<email address hidden>:/Volumes/Dados/Users/goolic/Downloads/byobu-3.2  $ echo "$BYOBU_PREFIX/bin"          
/bin

tried to mannualy add the ~/byobu/bin to the PATH:
export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin:/opt/local/sbin:/Volumes/Dados/Users/goolic/byobu/bin

thats the result:
<email address hidden>:/Volumes/Dados/Users/goolic/Documents  $ byobu
sed: 1: "/Volumes/Dados/Users/go ...": extra characters at the end of D command

Here is the make install exit anyways:

<email address hidden>:/Volumes/Dados/Users/goolic/Downloads/byobu-3.2  $ sudo make install
