You receive this bug because this package does not respect my system's RANLIB (x86_64-pc-linux-gnu-ranlib) and calls directly /usr/bin/ranlib
The possible solutions to fix this issue are:
1)Fix the buildsystem, if you can;
2)inherit toolchain-funcs and use tc-export RANLIB
3)inherit toolchain-funcs and use emake RANLIB="$(tc-getRANLIB)"
From the build log:
checking for ranlib... ranlib
