Hi,

This is a follow-up on the post I put out last week:

It turns out that the problem is in the binutils package.  When I
"downgraded" to binutils 2.5.2l.17, the programs linked correctly to
libX11, etc.  I skimmed through the release notes, but this didn't
seem to be mentioned.  Just thought that this might be interesting to
other people as well.  (BTW, I am running kernel 1.2.13).
