Comment(by NotFound):
In r40354 I added attempts to ldopen using the names libpcre.so and
libpcre.so.3 if the plain libpcre fails. I think the last attempt will fix
the problem, not because of the soname of the library but because of a
dynamic link with that name exists, and the libpcre.so link is provided by
the libpcre devel packages, not the plain libpcre ones, in a lot of
systems.
This is a generic problem for runtime linking, pkg-config and friends are
intended for compile time linking, not for dlopen'ing. Anyway, providing
the major version number of the intended library is not such a bad thing,
it can avoid attempts to use abi incompatible versions.
