That's simply not the case.
The engines aren't "libraries" as such (being modules), they're loaded using
dlopen(). Normal libraries are linked into the executable and resolved at load
time, by using the ld.so path mechanism. This is done by the ELF loader.
Since dlopen() requires a full path to load a library, that has to be
compiled in at build time.
Remember: The error in this case is the Debian repackaging of the i386
libgtk2.0-0, which uses the same library paths.
