Hello all,

I tried to install symbolic from within Octave.

Package ginac was not found in the pkg-config search path.
Perhaps you should add the directory containing `ginac.pc'
to the PKG_CONFIG_PATH environment variable
No package 'ginac' found

I have set the environment variable and used pkg-config --variable
path-to-pkg-build pkg-build, but still the installation fails.

I am using Octave 3.8> .

Thanks
