[Click] Compile issues on RHEL 6.4 (2.6.32)

[Keith Schoenefeld]

I'm running RHEL 6.4 with a RedHat kernel.  I've worked through
various compile issues working on the 2.0.1 release code, including
having to recompile the kernel from source with NR_CPUS set to 8
instead of 4096, adding the NETREG line to fixincludes.pl, etc.  I
have 2.0.1 compiling now with no issues, but once I install and run
insmod click.ko I get the error "insmod: error inserting 'click.ko':
-1 Cannot allocate memory".  I tried running strip -g as suggested in
another post, but then I get "insmod: error inserting 'click.ko': -1
Unknown symbol in module".  I've also tried using the latest git
repository.  Using the following configure command:

./configure --prefix=/opt/click-kohler-6aa1787 --disable-userlevel
--enable-multithread

I end up with the following errors (I ran make once to compile
everything that would compile, then again to just get the list of
errors):

I'm not sure where to go with the DEBUG_HASH, DEBUG_HASH2, etc. errors
and google hasn't helped me at all.  Does anyone have any
recommendations for getting this working?
