[dm-devel] Unable to build MPT 0.4.9

[--[ UxBoD ]--]

When attempting to build the RPM for the latest release I receive the error:

ake[2]: Leaving directory `/home/compuser/multipath-tools-0.4.9/libmultipath/checkers'
make[2]: Entering directory `/home/compuser/multipath-tools-0.4.9/multipath'

This is on a CentOS 5.4 system running kernel 2.6.28.7.  Am I missing a dependency ?
