Here's what I did to get it partially working on my AVLinux2rc2 (debian) installation:
export QT_DIR=/usr/lib/qt4 (not sure if this is needed)
then
QTDIR=/opt/lib/qt4 scons (not sure if this is needed)
it returned these errors:

scons: *** [hydrogen] Error 1
scons: building terminated because of errors.
pcuser@avl:/media/Data/src/hydrogen/0.9.5-beta1$
Then I upgraded the following packages:
libxslt1-dev (1.1.24-2) to 1.1.26-1
libxslt1.1 (1.1.24-2) to 1.1.26-1
and now it installed fine, only problem is no drumkits are installed by default.
Cheers!
