emerge --info

With the use flag 'static-libs' enabled for the package "dev-libs/protobuf-2.5.0", the -fPIC flag should be used to enable builds with the static library. Linking against the resultant static library gives relocations errors like:

/usr/lib/gcc/x86_64-pc-linux-gnu/4.8.3/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.3/../../../../lib64/libprotobuf.a(common.o): relocation R_X86_64_32S against `_ZTVN6google8protobuf7ClosureE' can not be used when making a shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-pc-linux-gnu/4.8.3/../../../../lib64/libprotobuf.a: could not read symbols: Bad value

Looking at the emerge output, it does seem to be the case that -fPIC is not present.

libtool: compile:  x86_64-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I. -I.. -pthread -Wall -Wwrite-strings -Woverloaded-virtual -Wno-sign-compare -O2 -pipe -c google/protobuf/stubs/common.cc -o common.o >/dev/null 2>&1

I've attacked my emerge --info dump

This appears to be fixed in 2.5.0-r2.
