If you copy it into /usr/local then all the paths are automatically 
sorted out. Otherwise to run from a different directory you need a 
number of variables. This is from test.sh in deb-light in the packaging 
repository:

basedir=$destdir/usr
export PATH=$basedir/bin:$basedir/local/bin:$PATH
export MYTHTVDIR=$basedir
export 
LD_LIBRARY_PATH=$basedir/lib:$basedir/share/mythtv/lib:$LD_LIBRARY_PATH
export PYTHONPATH=`ls -d $basedir/local/lib/python*/dist-packages`
export PERL5LIB=`ls -d $basedir/local/share/perl/*`${PERL5LIB:+:${PERL5LIB}}

test.sh can be used to run packages from the install location used with 
deb-light. See the deb-light readme.
