Upgrade of MrP under RH8 is not working properly

Everytime I launch an RPM for installing either MrP.7 or Mrp.8 a
dependency is found for "libmrproject = 0.6".  At first I assumed this
was the standard installation with RH8 since my standard install came
with MrP.6, but I've had difficulty varifying this.  Then I compiled the
libmrproject-0.6 source, ran "make install", and attempted then to
install both libmrproject-0.7.cf1.i386.rpm and
libmrproject-0.8.cf1.i386.rpm to no avail.  Please advise.  Thank you.
