Here we go ... answer from upstream ...

Wrong revision. This is the correct one of the actual changes you are
interested in here:

http://svn.linuxsampler.org/cgi-bin/viewvc.cgi?view=revision&revision=2572

In this revision several things happened. First of all, it added AKAI support
to libgig. Since the AKAI source files were based on libakai, which in turn
was and is released under LGPL, while the rest of libgig is released under GPL
terms, I had to split those libgig parts into separate .so files, to avoid any
license confusions.

Having a 2nd .so file built though, this triggered issues with the Debian
packaging scripts as far as I can remember. So I was forced to move the .so
files from /usr/lib to a common subdirectory /usr/lib/libgig.

And by the way, the Debian packaging scripts coming with the libgig upstream
version build, install, and behave just fine on Debian! :-)

As you might see in the Debian packaging scripts coming with the libgig
upstream version there are postinst and postrm rules which ensure that
/usr/lib/libgig is added / removed to /etc/ld.so.conf.

So what we can do?
