/usr/local/compat/pkg existed but I followed your advice and removed it.
/var/db/pkg was empty when I checked it.
I proceeded to trying to install /usr/ports/lang/ruby18 by make clean
and then make install clean. It failed with the same error as in my
previous attempts.

However, some packages built correctly: shells/bash, lang/perl5.8,
sysutils/ezjail and www/apache.

I really wanted to take portmaster into consideration (it's a better
alternative to portupgrade in my opinion also), but sysutils/puppet uses
portupgrade as its backend and I use puppet on my servers. So I'm stuck
with portupgrade.

I also noticed when compiling other programs, that the line contains the
following arguments: -fPIC -DPIC, while compiling ruby18, it only
contains -fPIC. I added -DPIC to /etc/make.conf, so that the CFLAGS line
would look like:
CFLAGS?= -O2 -fPIC -DPIC -pipe
After that, the compiler output lines still look like:
cc -O2 -fno-strict-aliasing -pipe   -fPIC  -DRUBY_EXPORT -I. -I.   -c
variable.c
and fails as in my previous attempts.
