In order to build it, I've had to add the following missing
build requirements:

  libtool (as before)
  openssl-devel

Try to get upstream to ship a good tarball, where you don't need to run
autogen.sh.

Well, you have moved _all_ shared libraries into the -devel packages, not
just .a/.la/.so from /usr/lib, which are only needed for development.

Generally, *.so files are symlinks pointing to versioned *.so.* libraries
(note the subtle difference, *.so is not equal to *.so.*). Unless the *.so
files are accessed at run-time (e.g. via dlopen), they are only needed at
compile/link-time (option -lfoo in compiler command line means to link
against libfoo.so). If you wanted to install multiple versions of a
library at once, e.g. libfoo.so.0 and libfoo.so.1, you could not have
multiple *.so symlinks with the same file name pointing to different files
(should it be libfoo.so -> libfoo.so.0 or libfoo.so -> libfoo.so.1?).
That's why *.so files, which are needed at compile/link-time only, usually
are put into -devel packages.

Programs are linked against versioned *.so.* libraries. These dependencies
are caught automatically by rpmbuild (see "rpm --query --requires
packagename").  Good programs, which open libraries at run-time, open
versioned files too, and not non-versioned ones like "libfoo.so". Or they
put run-time loaded non-versioned *.so libs into private sub-directories
and not store "modules" ("plugins" or hula "snapins") in the root of
%{_libdir}.

Of course, where you are unsure and where parallel installation of
multiple versions is not planned, you could include all *.so symlinks
in the main package and don't worry.


In detail:

-rwxr-xr-x root  root     68156 /usr/lib/hulamdb/libmdbfile.so

This run-time loaded *.so file and its directory belong into the main
package, the static archive *.a is not needed.

A core hula library. The *.a/*.so files can be moved into -devel package.
The *.so.* files are needed in the main package. The executables are
linked against them. See package dependencies quoted above.

-rwxr-xr-x root  root     23604 /usr/lib/libhulamdb.so.0.0.0

-rwxr-xr-x root  root      8076 /usr/lib/libwastdobj.so.0.0.0

These three above are webadmin agent modules, which belong into the main
package. *.a files not needed, since *.so files are loaded at run-time,
and *.so symlinks point to *.so.*, so all but *.a files are needed here.

Same as with the libwa*.  Files *.a not needed, only the *.so are needed
in the main package here.
