it seems you are using a compiled GiNaC version 1.3.x with GiNaC headers 
from version 1.4.x.

Why not #include <ginac/ginac.h> ??

Did you copy ginac.h by hand somewhere? Or did you install GiNaC locally 
for yourself but forgot to set the correct compiler flags (so that the 
linking is actually done against a system-wide installation of GinaC)?
