Trouble building on PPC

[Birch P. Browning]

I get the following error when trying to build either fix2 or cvs:

kill.c: In function `int lyx::kill(int, int)':
kill.c:10: implicit devlaration of function `int kill(...)'
make[3]: *** [kill.lo] Error 1
make[2]: *** [all-recursive] Error 2
make[1]: *** [all-recursive-am] Error 2
make: *** [all-recursive] Error 1

Is this a problem with the lyx source or with the library setup on my 
machine?
