This sounds line it's in some way your ldconfig setup.

Is /bin/echo the only file you can find that links thus? Actually, in
this case, IIUC, echo is rarely called if you use bash (and perhaps
others) because bash provides its own echo function. Out of curiosity,
for any of these programs that have this odd linkage, find the package
that contains this program. ( use dpkg -S <programname>). Then, do a
dpkg --contents <deb-in-archive> | grep <some-part-of-program> for some
deb you have in the archive, and compare the size, etc of the
corresponding files. It appears to me that you have an oddball echo.

Then your libraries _ought_ to be correct. I've come all the way from
potato to sarge by simply upgrading.

I have only the X11 entry in mine. I wonder.. I'm not that proficient
with libc, but could it be that something in one of these directories is
intercepting and redirecting your search path???

As an experiment, in light of my previous paragraph, if you're not
afraid to tinker with it, how about temporarily removing at least the
atlas and local libs from the path and see if that helps?
