- Remove useless `pathfix' from USES and add more useful `localbase'
- Prefer AMAROK_CONFIGURE_ON over AMAROK_CONFIGURE_ENABLE for consistency
with other options (configure arguments)
- Use option-dependent `post-install' target and remove needless .include
<bsd.port.options.mk> thanks to that
- Unroll a .for loop over one file and optimize away another .for loop
by using implicit iteration over ${PORTDOCS} instead
