Assuming you're on Ubuntu(or possibly Debian) by looking at
packages.ubuntu.com one can see that the package in question hasn't had
that name since Hardy (8.04)
http://packages.ubuntu.com/search?suite=default&section=all&arch=any&searchon=names&keywords=libg2c

Poking around there appear to be some solutions:
https://bugs.launchpad.net/ubuntu/+source/gcc-3.4/+bug/249991

1. use gfortran instead of g77
2. use ubuntu 8.04 which has the package
3. download the old package from the web and force the install of it

"By downloading the deb file from
http://packages.ubuntu.com/jaunty/libg2c0

and then running
sudo dpkg --force-depends -i libg2c0_3.4.6-8ubuntu2_amd64.deb"
http://ubuntuforums.org/showthread.php?t=1346528

Long term there's some underlying discussions about updating the source
code of the application to drop that dependency as it seems to not be
required if you use gcc3.4+ and gfortran (Guess from reading those links).

Thanks,
