>Description:

Recently I was unable to install anything from ports.  Like for example 
on just this random port that wasn't previously installed...

cd /usr/ports/devel/p5-Class-Factory-Util
make install
===>  Installing for p5-Class-Factory-Util-1.4
===>   Generating temporary packing list
===>  Checking if devel/p5-Class-Factory-Util already installed
*** Error code 1

Stop in /usr/ports/devel/p5-Class-Factory-Util.

Thinking that I was out of date and something had updated in the system I 
did a fresh cvsup/build/installworld and had the same result.

I then debugged it a bit and found it ran the command

/usr/sbin/pkg_info -q -O devel/p5-Class-Factory-Util

So I ran it by hand since that was being sent to /dev/null

It returned

pkg_info: /var/db/pkg/pear-Console_Getopt-1.0/+CONTENTS: No such file or
directory

So I did a pkg_delete on that port (I didn't need it) and it told me it wasn't
installed.  However the directory existed and had just a +REQUIRED_BY file
in there.  I removed it (directory and all) and ports could once again 
install.

It seems that one port didn't fully get cleaned up when it was removed.

>How-To-Repeat:

As a test I took a port I didn't need anymore and removed it.  Then in 
/var/db/pkg I recreated it's directory and just did a touch +REQUIRED_BY
in that directory.  I then couldn't install things from ports again till
that was removed.

>Fix:

A workaround is to of course find the offending uncorrectly deinstalled
port and remove it's directory.
