packages certainly would be nice, i have to do all kinds of patching
to make the damn thing go into /usr/local where it belongs.  there is
more to life then .rpm sheesh....

hmm i don't have such a file on my system and was able to compile
MOL.  the makefile does use the kernel headers in
/usr/src/linux/include (i have a /usr/src/linux symlink to
/usr/local/src/linux which is a link to /usr/local/src/linux-2.2.17.) 

i do however have to at least copy my .config back to the kenrel
source tree and run make oldconfig && make dep.  otherwise the mol
modules get miscompiled.

yup i don't know why this is still broken it *should* fail everywhere
but i suspect nobody actually compiles this bugger themselves.  adding
-lelf to the linker arguments in Rules.make seems to work fine... 

i enclosed a patch i made to fix things for my /usr/local setup, and
to fix the insecure permissions it insists on installing with, along
with fixing some insecure /tmp handling (not all of it im sure, i
think the program itself has insecure tmp handling too, have not
checked.)

i have not really refined my changes enough to send upstream yet, feel
free to improve.
