[IRCServices Coding] Compiling error in v5.0.0

[Ganja51]

When trying to update to v5.0.0 I of course first run ./configure. Once that
is done I try to run gmake and get this error:

sh version.sh
gcc  -O2 -fno-strict-aliasing -Wall -Wmissing-prototypes -g -c version.c -o
version.o
gmake[1]: Entering directory `/usr/home/ganja/ircservices-5.0.0/modules'
gmake[2]: Entering directory

gcc: vfork: Resource temporarily unavailable
gmake[4]: *** [.compiled-main.o] Error 1

gmake[1]: *** [all-dynamic] Error 2
gmake[1]: Leaving directory `/usr/home/ganja/ircservices-5.0.0/modules'
gmake: *** [modules] Error 2

The box is running FreeBSD 4.7-PRERELEASE. The thing is, pre15 compiled
perfectly, and still does, but the release of v5.0.0 doesn't. Any
suggestions?
