Gotcha. Somebody else pointed this out, too. I wasn't aware of the
convention. Thx.

They *can* be loadable modules. Normally, we just link them in. But if you
pass --enable-dso to ./configure, then it will stop linking them in. When
doing so, however, the DSO loader must be able to find them. I'm not sure
what the Linux rules are for that. I suspect the paths in ld.so.conf and/or
LD_LIBRARY_PATH.

How were the Mandrake packages set up? Do they use that configure switch?

[looking in packages/mandrake/ ...]

Ah. I see that it *is* used.

And since the switch *is* active, then yes: the .so will be needed.

Yah, sounds about right. Any ideas on how to get the system to "look in the
right place" ? It it simply a matter of passing an absolute path to the
loader?
