not sure, but this sounds like a job for install_name_tool to adjust the
loader_path of the dylib. Off the top of my head (this most certainly
isn't completely correct, but should give a rough idea):

install_name_tool -id @loader_path/lib/libpcre.1.dylib
/path/to/pcre-any-any/lib/libpcre.1.dylib

The equivalent needs to be done for each binary actually loading the dylib:

install_name_tool -change libpcre.1.dylib
@loader_path/lib/libpcre.1.dylib /path/to/binary_or_so


Maybe something like the above can also be accomplished by otool during
the build, but I haven't looked into it.
