Re: pre-compiled binaries want libg2c.so

Mary,

Thanks for the help. I understand the issue o having many
dependencies. I will try to get the gcc 3.4.X environment back again
before I ask for your help.

It would great to see all of UCAR/NCAR go open source on the codes we
develop. NCL and PyNGL(NIO) would be good starting points. One
positive result is that users could further the development of these
tools and make them even more useful and at a faster pace.
