I've built perl, adding an option ``with_shared'' to the perl.spec file.
This then adds ``-Duseshrplib="true"'' to the ./Configure, and does some
tweaking to insure that the libperl.so file is available during the build
process, and installed on %{l_prefix}/lib. The attached patch handles this
(and enables GDBM_File which we use locally since we have a backwards
compatibility problem with many of our installed systems):
1. Enables gdbm.
2. Disables old gbm and ndbm because they were breaking when I was
building on FreeBSD 4.8.
3. Uses ``-Aprepend'' to add %{l_prefix}/lib to Configure since the
freebsd hints file hides the Dglibpth.
4. Adds LD_LIBRARY_PATH for %install processing if building with shared
libraries.
5. Links the %archlib/CORE/libperl.so file to %{l_prefix}/lib.
These patches are working on FreeBSD, but I haven't tested them on any
other systems yet.

It's really fairly simple. The client program (e.g. openoffice.org)
dynamically links to the libodbc.so library (or whatever the OS uses for
dynamic libraries). The %{l_prefix}/etc/unixodbc/{odbc.ini,odbcist.ini}
files are used to specify databases and attributes such as user and
password. The database requires a path to a dynamic library to reference
that particular type (e.g. myodbc, java, postgressql).
