Unfortunately I will not support Fedora, but if anyone is willing to put forth the effort to build an rpm I will put it on sourceforge.
In order to compile you need Qt 4.5, and all the associated tools including qmake. If you run qmake in the trunk directory, it should generate makefiles for the entire project. At that point you can type "make" and it will compile all the plugins as well as the executable.
To compile you will need:
Qt 4.5 development libraries, in addition to the default:
Phonon, WebKit, sql, qt-sqlite,
sqlite3 development libraries
taglib > 1.4 development libraries.
Sorry it took me so long to see this message.
