When I try to emerge vamos, I get the linker error shown below. It appears to be having trouble linking to plib, but the command options appear to list all of the necessary libraries. I have plib-1.8.4 installed, and I just re-emerged it to make sure it was compiled with the same compiler.

I figured out that I had old plib libraries in /usr/local, and those headers were being used but the linker was attempting to link against the newer libraries in /usr. Once I removed the old stuff in /usr/local, everything emerged without problem.
