It turns out to be a long story, because both the gdbm and db
libraries offer ndbm emulation, which is the interface
that apache actually uses, so when you build mod_perl you
end up with whichever library was linked first by the
perl compile. If you build apache without mod_perl you
end up with whatever appears to be be your ndbm library
which will vary between systems, and especially Linux
distributions. Some use gdbm - RedHat uses db but seems
to have switched to the file-incompatible 2.x version in
their 6.0 release. You may have to work a bit to get both
apache and perl to use the same library and you are likely
to have trouble copying the dbm file from one system to
another or even using it after an upgrade.
