Nice to see, that I'm no longer the only one who tries to setup mod_perl
and sybperl on a linux box.

Unfortunately, I have no good news for you. There seems to be a conflict
between the elf-port of Sybase's client-libraries and the c-libraries
apache/mod_perl use.

I just repost the steps of my attempts to make it run.

All my attempts to receive new versions of the client libraries from Sybase
failed. They dont seem to be realy interested in the linux community. One
final idea of mine is to set up a linux box with a.out-support and the
old-style c-libraries. Then build perl, sybperl, apache and mod_perl on
such a linux-box and use there Sybase's original client libraries. But
unfortunatly I've experience in perl programming, but have no idea how to
get this a.out-linux-environment.

Hope this helps.

Would be great to hear/read that you come further and how!.
