Ken, thanks. I've posted this problem twice to this list and gotten  
nothing, and this morning  you give me...well not me exactly...the 
answer. I assumed that when you said
"

To fix this, apt-get install --reinstall rubygems, and get rid of any 
rubygems stuff you may find in /usr/local

"
you got that backwards. In any case, I removed the rubygems stuff in 
/usr/local and THEN did the reinstall. Now for the first time in 4 days 
I have  working rubygems. Man...this needs to be written down somewhere. 
Like in my notes. So shall it be.

Thanks again.

Tom
