That's right.

This is a canonical problem in ELF.

For the ELF standard in the current version as supported by the tool, your
only way to do it if you use non-standard paths (paths not searched
automatically by the linker) is to use the --rpath linker option (something
like "-Wl,-rpath=/home/daniel/install/lib", but that has the undesired side
effect that it is not overridable at runtime later-on.

The upcoming new version of the ELF standard allows with runpath a similar
effect, but with lower precedence.

In a strict sense, gpgme-config should add rpath for non-standard paths. 
People hate that, though, because of the precedence problem.

You have digged out a hot potato here :)

Thanks,
Marcus
