sysctl -n compat.ia32.maxvmem

Hello list,

I was forced to run -CURRENT because no other version booted in my new
box. 
Running 10.0-CURRENT FreeBSD 10.0-CURRENT #1: Wed Jun 12 15:23:10 CDT 2013.

I'm getting this:

# portupgrade -a
make: "Mk/Mk/bsd.port.mk" line 1638: warning: Couldn't read shell's
output for "if /sbin/sysctl -n compat.ia32.maxvmem >/dev/null 2>&1;
then echo YES; fi" make: "/usr/ports/Mk/bsd.port.mk" line 1638:
warning: Couldn't read shell's output for "if /sbin/sysctl -n
compat.ia32.maxvmem >/dev/null 2>&1; then echo YES; fi" make:
"Mk/Mk/bsd.port.mk" line 1638: warning: Couldn't read shell's output
for "if /sbin/sysctl -n compat.ia32.maxvmem >/dev/null 2>&1; then echo
YES; fi" make: "Mk/Mk/bsd.port.mk" line 1638: warning: Couldn't read
shell's output for "if /sbin/sysctl -n compat.ia32.maxvmem >/dev/null
2>&1; then echo YES; fi"
...

After getting tons of messages like this portupgrade actually works.
Sure enough, I do not have COMPAT_FREEBSD32 enabled in kernel, I guess
this is what it is about?
