Make sure you find out if the libs are GPL'ed or LGPL'ed, its a big
difference. 
If they are GPL'ed and if you link to it from your application
you have to be compatible with the GPL. 
If they are LGPL'ed you can link to them from your application without
being forced to be compatible with the GPL. You can use whatever license
you want.
