I get this same error on net-mail/topal-75 -- it seems to be an issue with the compilation environment, as gcc has installed the .so that isn't being found:

$ equery files gcc | grep -i liblto
/usr/libexec/gcc/x86_64-pc-linux-gnu/4.8.5/liblto_plugin.la
/usr/libexec/gcc/x86_64-pc-linux-gnu/4.8.5/liblto_plugin.so
/usr/libexec/gcc/x86_64-pc-linux-gnu/4.8.5/liblto_plugin.so.0
/usr/libexec/gcc/x86_64-pc-linux-gnu/4.8.5/liblto_plugin.so.0.0.0

Did you ever find a solution to this?

Its an issue in gnat-gcc built with lto support. Lets keep discussion to one bug..
