Yea i think as (i mentioned on VWR-4491) that XMLRPCEPI_FIND_REQUIRED
should be true and this a bug here.

I would guess xmlrpc-epi.so as there are many other xmlrpc libraries
available and it minimisies collision chances with another installed
library and it is obvious which xmlrpc library you are looking at.

Also this is what the default ./configure make make install scripts generate.

As this is not an offical Gentoo pacakge I would see if you can get
the packager to update it.

You don't

This is the correct behavior for shared libraries

It is usual on distro based systems to have a lib and a develo
pacakge. The lib contains xmlrpc-epi.so.0 which has the so name
appended and the develo package contains the headers AND a
xmlrpc-epi.so symlink. Applications would build against xmlrpc-epi.so
then due to the symlink the binary becomes dependent on
xmlrpc-epi.so.0.
