Biber cannot find a shared library

[Nelson H. F. Beebe]

M. Wierdl asks about a missing libnsl.so.1 in biber on Fedora 39.

I just checked one of my Fedora 39 systems and found that it has
more recent generation numbers:

	% file /lib64/libnsl.so*
	/lib64/libnsl.so.3:     symbolic link to libnsl.so.3.0.0
	/lib64/libnsl.so.3.0.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked,
	BuildID[sha1]=dc26e257974a037b378927c4b91e57bce85a7e6e, stripped

Most cases of minor version differences in shared libraries can be trivially fixed
by a symlink.

If you have root access on the machine

	# ln -s libnsl.so.3 /lib64/libnsl.so.1

should fix it for everyone on that machine.

If not, then

	$ mkdir $HOME/lib
	$ ln -s /lib64/libnsl.so.3 libnsl.so.1
	$ export LD_LIBRARY_PATH $HOME/lib
	$ biber

should work for a single user.

Shared library version number differences in GNU/Linux distros are a
pain for software that is built on one system, and expected to work on
many others.  Also, most library packages fail to supply static
libraries (lib*.a), and only supply dynamic ones (lib*.so*), leading
to this problem.
