BC 5.3 on RH 8.0

Wrote the following to Sasha today:

I'm still trying to build BC on RH 8.0. Since I was successful at building BC 5.3 on RH 6.1 I figured I oughta try building BC 5.3 on RH 8.0. I am also building starting as root.

I've tried twice now and it continues to fail in step 4.1 building the kernel. The following appears in build_kernel.log:

+ echo BUILDING A KERNEL FOR pmac_g5...
+ cp /build/bluecat/build/20050429/cdt/src/bluecat/SOURCES/bluecat-pmac_g5.config arch/ppc/defconfig
+ rm -f .config
+ make mrproper
+ make oldconfig
/bin/sh: line 1: bc_native_gcc: command not found
make[1]: *** [scripts/basic/fixdep] Error 127
make: *** [scripts_basic] Error 2
error: Bad exit status from /build/bluecat/build/20050429/var/tmp/rpm-tmp.94728 (%build)
    Bad exit status from /build/bluecat/build/20050429/var/tmp/rpm-tmp.94728 (%build)

Apparently var/tmp/rpm-tmp.94728 is a build script built on the fly then executed. bc_native_gcc does exist in /usr/src/bluecat/eng/bluecat/bc_misc but this script can't find it.

Ideas?
