>Description:
During an attempt to perform binary package updates, I discovered that portmaster still probes the /usr/ports directory looking for a ports tree.  In my case, /usr/ports was an empty directory.

My command line looked like:

env MASTER_SITE_INDEX=http://pkgbuilder/tb/packages/8.2-FreeBSD-SHN/ PACKAGES=/tmp INDEXDIR=/tmp PACKAGESITE=http://pkgbuilder/tb/packages/8.2-FreeBSD-SHN/ portmaster -PP --index-only puppet

This resulted in:

===>>> The ports directory (/usr/ports) does not seem to contain a ports tree
===>>> Aborting update

Terminated

After renaming /usr/ports to /usr/ports.orig, portmaster proceeded with no problem.
>How-To-Repeat:
Create an empty directory /usr/ports, then perform a binary package upgrade with "portmaster -PP --index-only ...".
