Building 2.4.2 on OpenBSD 3.8

[Dan M]

I've been working with python 2.2.3 for the last couple of weeks, but
would like to move up to 2.4. I grabbed the 2.4.2 tarball and attempted to
install, but I get:

gcc -pthread -c -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -I. -I./Include  -DPy_BUILD_CORE -o Modules/python.o Modules/python.c
In file included from /usr/include/sys/select.h:38,
                 from Include/pyport.h:116,
                 from Include/Python.h:55,
                 from Modules/python.c:3:
/usr/include/sys/event.h:53: error: syntax error before "u_int"
/usr/include/sys/event.h:55: error: syntax error before "u_short"
*** Error code 1

Stop in /usr/local/src/Python-2.4.2.

immediately upon running "make". I took at look at event.h to see if I
could find and fix the problem, but the error isn't immediately apparent
to me.

Has anyone successfully built 2.4.2 on OpenBSD? If so, how did you do it?
