CentOS - Jan 2005 - rpmbuild --rebuild --define 'buildklips 1' openswan-2.3.0-1rhel.src.rpm quirk

rpmbuild --rebuild --define 'buildklips 1' openswan-2.3.0-1rhel.src.rpm 

The present kernel configuration has modules disabled.
Type 'make config' and enable loadable module support.
Then build a kernel with module support enabled.

make[1]: *** [modules] Error 1
make[1]: Leaving directory `/usr/src/linux-2.4.21-27.0.1.EL'
make: *** [module26] Error 2
make: Leaving directory `/usr/src/redhat/BUILD/openswan-2.3.0'
error: Bad exit status from /var/tmp/rpm-tmp.43563 (%build)

# Loadable module support
#
CONFIG_MODULES=y
CONFIG_MODVERSIONS=y
CONFIG_KMOD=y

I am tad perplexed here, any ideas?

Regards,
Ted
