Thank you!

I've been bashing my head against this for some time now.

I *am* setting LD_LIBRARY_PATH (using a shell script wrapper around a
Python CGI script), but I guess it's non-Sybase libs that are not being
found.

With hindsight, it seems blindingly obvious that I should have rote-copied
the shell environment and then experimented to track this down...  I guess
my mental block was assuming that some obscure Solaris security feature
was to blame.
