yes I've seen that the build process is ok and that's a good thing.

Aren't the --with-wx* flags you gave to us useable for this ?
I personnaly use them each time I build pga3 like this:
--with-wx=/usr --with-wx-config=wx-config

mmmh, I missed that part of the process, but:
wx-config --libs gives some informations. In my case :

thanks! :)
