I think this is exactly right.  If you have shared libraries installed
in /usr/quist/lib, you need to tell your system about it, preferably
globally.

We have addressed this issue by including the version number of
libguilereadline in its name so that 1.4 and 1.6 will not confuse each
others libraries.  We hope to have a more elegant solution in 1.8.
