Integration of RMAN with virtual tape library

Hello,
I would like to test something about RMAN and writing directly to tape. For this I installed mhvtl, a virtual tape library. The installation was pretty easy. http://sites.google.com/site/linuxvtl2/
RMAN does not recognize any tape in the system.
ORA-19554: error allocating device, device type: SBT_TAPE, device name:
ORA-27211: Failed to load Media Management Library
What I found out is that in order to make backups to a media manager, RMAN must communicate with a media management library, which is a 3rd party library that is not supplied by Oracle. So I guess unless there is a Oracle MML library available for mtx I' out of luck here.
Any ideas? Thanks!
rpm -ivh mhvtl-0.18-13.x86_64.rpm
rpm -ivh mhvtl-0.18-13.src.rpm
cd /usr/src/redhat/SOURCES/
tar zxvf ../SOURCES/mhvtl-2011-01-11.tgz
cd mhvtl-0.18/kernel
make
make install
/etc/init.d/mhvtl start
yum install mtx
The tape library and using it for backup from system seems to work fine:
# mtx status
Storage Changer /dev/changer:4 Drives, 43 Slots ( 4 Import/Export )
Data Transfer Element 0:Full (Storage Element 1 Loaded):VolumeTag = E03001L4
etc.
# mtx load 1
Drive 0 Full (Storage Element 1 loaded)
# tar cf /dev/ntape ./
# tar tvf /dev/ntape
