[PlanetCCRMA] Hydrogen on FC2 and apt problems also

[flump00 at breathe.com]

Hi there all!
I've just installed the ccrma on FC2, and I've noticed that there isn't jack 
support compiled in to Hydrogen. Why not?
I know that there is apparently some real time problems with jack on FC2, 
but why is there no jack support for hydrogen? 

"Nevermind", thought I, "I'll build it myself from the sourcecode, enabling 
jack support. I'll get the devel files from online, as it'll need some 
development libraries that I don't have". But alas! Attempting to do an:
apt-get install planetccrma-audiovideoapps-devel 

whinges thus: 

The following packages have unmet dependencies:
 planetccrma-audiovideoapps-devel: Depends: a52dec-devel but it is not going 
to be installed
                                   Depends: imlib2-devel but it is not going 
to be installed
                                   Depends: libmad-devel but it is not going 
to be installed
                                   Depends: xosd-devel but it is not going 
to be installed
E: Broken packages 

Any news? Some help would be greatly appreciated, as I'd love to be able to 
run Hydrogen with jack. 

Thanks again
