Re: ncarg on Mac OS X 10.4.8

After some additional investigation and tinkering, it appears that the
root of the problem is g77 3.4.3 is not fully compatible with gcc 4.0.1
on Mac OS X 10.4.8 This is because the g77 compiler has hardwired code
to look for the 4.0.0 libraries and is unable to locate the 4.0.1
libraries. I was able to patch this by creating a symbolic link to fool
g77 into using the 4.0.1 libraries.

To summarize, there does not appear to be a problem with the new Xcode
2.4.2 or gcc 4.0.1 with NCAR Graphics. There is a problem between gcc
4.0.1 and g77 3.4.3 on the Mac.
