need dmraid install help on fc4

I'm trying to build dmraid but this 'diet' stuff is giving me
indigestion.  I installed dietlibc-lib:

# rpm -qa |grep diet
dietlibc-0.29-2.fc4
dietlibc-lib-0.29-2.fc4

but still getting a build error:

# rpmbuild --rebuild dmraid-1.0.0.rc9-1.src.rpm 
.....
diet gcc -o dmraid dmraid.o commands.o toollib.o  -rdynamic -L../lib \
      -L/var/tmp/dmraid-1.0.0.rc9/lib -ldmraid -ldevmapper_dietc
-lselinux
/usr/bin/ld: cannot find -ldevmapper_dietc
collect2: ld returned 1 exit status
make[1]: *** [dmraid] Error 1
make[1]: Leaving directory
`/usr/src/redhat/BUILD/dmraid/1.0.0.rc9/tools'
make: *** [tools] Error 2
error: Bad exit status from /var/tmp/rpm-tmp.81092 (%build)


RPM build errors:
    Bad exit status from /var/tmp/rpm-tmp.81092 (%build)

so I'm lost...any help is appreciated.
