Portsdb error

[Michael A. Alestock]

Hello,

I use the PORTSDB (-Uu) command as part of upgrading my ports collection.  However, while trying to run this command today I got the following error.....

bsd# portsdb -Uu
/usr/local/sbin/portsdb:35:in `require': No such file to load -- pkgtools (LoadError)
        from /usr/local/sbin/portsdb:35
bsd#

I've NEVER had this kind of error before with Portsdb.  I even doublechecked to make sure the binary was installed....

bsd# whereis portsdb
portsdb: /usr/local/sbin/portsdb /usr/local/man/man1/portsdb.1.gz
bsd#

Any clue to what's going on here?? 

THANKS....
