This is a common misconception. The GPL does NOT prevent you writing 
your own software that *uses* the GPL package and licensing it in any 
way you wish. Ie, the fact that your software calls "xm" does *NOT* 
mean you have to GPL your own software.
It is no different to running a commercial package on a Linux system. 
The fact that Linux (and the various tools etc) are GPL does not mean 
your software has to be.
Where you do have to be careful is if you make some GPL software an 
integral part of your package - eg by including some GPL source in 
your project. This would make your code a derived work which would 
also have to be GPL.
