Got it working. here's how:
CFLAGS='-I/usr/kerberos/include' ./configure --with-krb5 KRB5CFLAGS="-I/usr/kerberos/include" KRB5LIBS="-L/usr/kerberos/lib -lcrypto -lkrb5"
make && make install
create/copy/symlink the following files into existence:
/usr/local/etc/openafs/cache
/usr/local/etc/openafs/ThisCell
/usr/local/etc/openafs/CellServDB
/usr/local/etc/openafs/C -> /usr/local/sbin/afsd
/usr/local/etc/openafs/cacheinfo
/usr/local/etc/openafs/afsd -> /usr/local/sbin/afsd
add '/usr/kerberos/lib' to /etc/ld.so.conf
ldconfig
insmod /usr/local/lib/openafs/libafs-2.6.29.6.ko
afsd
aklog
