 This is excellent work.  I myself attempted the update a few weeks ago, 
 and got bogged down.
 
 I got it to build successfully.
 
 However, when I ran the program netgen, I received an error message
 
 result = couldn't read file "./ng.tcl": no such file or directory
 Make sure to set environment variable NETGENDIR to directory containing 
 ng.tcl
 
 Doesn't it make sense to make sure that NETGENDIR defaults to 
 /usr/local/bin?
