building kernels under mach (FC2)?

Hi all, anyone out there building kernels in a mach chroot? I'm trying
and failing :-) I'm building a version of 2.6.6 and the build dies with:

+ make ARCH=i386 nonint_oldconfig
./scripts/kconfig/conf: error while loading shared libraries:
libkconfig.so: cannot open shared object file: No such file or directory
make[1]: *** [nonint_oldconfig] Error 127
make: *** [nonint_oldconfig] Error 2
error: Bad exit status from /var/tmp/rpm-tmp.28305 (%prep)
 
Now, if I chroot into the proper root after the build fails, su -
machbuild, cd to the right directory and do a "make ARCH=i386
nonint_oldconfig" again, I see no errors..., ldd's of the executables I
can see do not return errors as well :-(
