Hi! The problem with the package is that it doesn't link to a specific mysql or mariadb client library, but searches for it in runtime by name and loads it dynamically. So we can't use the shlibdeps mechanism to construct the dependencies list as usual.
I'd suggest to add another alternative libmariadb3 (with a patch which adds libmariadb.so.3 to the library search list). We'll upload the fixed version shortly. Cheers! -- Sergei Golovan
