RooFit vs make debian: 1:0

Dear RooFit/Stat experts,

I am trying to make a lenny debian package from ROOT 5.28. While standard compilation had worked nicely, making the debian package crashes on the following items:

roofit/histfactory/src/G__HistFactory.o: In function PiecewiseInterpolation::ShowMembers(TMemberInspector&)': G__HistFactory.cxx:(.text+0x1433e): undefined reference toRooAbsReal::ShowMembers(TMemberInspector&)’

HistoToWorkspaceFactory.cxx:(.text+0x1143a): undefined reference to RooCmdArg::~RooCmdArg()' ... LinInterpVar.cxx:(.text+0x6b2): undefined reference toRooListProxy::~RooListProxy()’

PiecewiseInterpolation.cxx:(.text+0x845): undefined reference to `RooLinkedList::MakeIterator(bool) const’

I ran “make debian” with build/package/debian/rules containing the same configure options, which worked before successfully with usual “make”:

CONFOPTIONS :=–enable-cintex
–with-glew-incdir=/usr/include/GL \

Any idea what could be updated, probably in the build/package/debian location, please?
Thanks in advance for any hint or reply.
