Cannot install Baldur's Gate on NixOS

Hi, when I try to install Baldur’s Gate original version from GOG on NixOS, I get this error:

I can’t move /home/felix/Games/gog/baldurs-gate-the-original-saga/tmp/data/noarch/prefix/drive_c/GOG Games/Baldur’s Gate, it does not exist

Here are the logs:

As you can see, the error message is misleading: the issue is due to the fact that unzip cannot load the right shared library libbz2.so, so it cannot unpack the archive.

The reason is that on NixOS, the system is stripped from its shared objects: they are packaged with the binaries through the packages scripts. That means that one cannot expect to download a binary and execute it directly.

My question is: what workaround can I use? My bet is that I must rewrite the script to use the unzip from my system, but maybe there is a simpler way. Also, I don’t really know how to rewrite the script to include that change, if needed.
