RE: undefined symbol: random_source_register during kernel compilation

Good morning!
I found a problem rather quickly: the compilation complains about a missing libcasper.h file. (/usr/include/capsicum_helpers.h references libcasper.h, and not from the sources but from the installed system.

The problem is that casper is a feature which can be switched off (and on again) in /etc/src.conf, but I suppose that if I switch it BACK, thatis if I want it to compile casper again (remove the WITHOUT_CASPER=YES line from src.conf, e.g.), then the sources for casper should be there somewhere in my freshly synchonized source tree.

(and it is: libcasper.h is in /usr/src/lib/libcasper/libcasper  but compilation supposes that it has already been installed into /usr/include).

Now I try to compile GENERIC with my original src.conf, which switches off the CASPER, and see what happens.

are you able to build GENERIC?  if so might be worth looking at the 
delta's b/w GENERIC and your custom configuration and trying to zero in 
on what may be causing this to fail.
