installing libgl1-mesa-swx11-dev wants to remove x and mesa

["Colm Connolly" <colmconn@gmail.com>]

Hi everybody,

I'm trying to install libgl1-mesa-swx11-dev so I can get GL/GLwDrawA.h
for some code I need to compile, however this requires (according to
aptitude) removing pretty much all of X.

Is it possible to install libgl1-mesa-swx11-dev without nuking X in the process?

This is what aptitude says:

root@darwin:~# aptitude -s install libgl1-mesa-swx11-dev
