I started looking into it a few days ago but didn't really follow through. 
What I found was that EINTR is defined in /usr/include/linux/errno.h but the 
file that is failing, /libipsec/pfkey.c, just has #include "errno.h". There 
are various errno.h files around including one for each arch type in the 
kernel source, one in /usr/include/asm, /usr/include/sys, and /usr/include. 
It appears that the wrong one is being included, which I think is what Robert 
is alluding to with the CFLAGS option. I didn't find any answers though.
