FreeBSD: numba/np/ufunc/workqueue.c:30:10: fatal error: 'alloca.h' file not found

So after fixing the FreeBSD build in llvmlite, I get a somewhat weird message upon trying to install numba.

The compilation error is:

numba/np/ufunc/workqueue.c:30:10: fatal error: 'alloca.h' file not found

Upon searching for alloca.h, I found a similar file in /usr/local/include/glib-2.0/glib/galloca.h.

Any suggestions?

Okay, so the FreeBSD ports (compiling numba from the source) includes a diff to workqueue.c:

--- numba/npyufunc/workqueue.c.orig     2018-11-14 22:14:35 UTC
+++ numba/npyufunc/workqueue.c
@@ -19,7 +19,11 @@ race condition.

 #include <unistd.h>
+#if defined(__FreeBSD__)

 #endif

Please add this to workqueue.c so it can compile effortlessly on FreeBSD.
