ideally, we should figure out why there’s a difference if it used to 
pass, but I’m way too lazy to do that. :-(

I don’t think I did anything special. I just cloned the repo, checked 
out the Version_2.7.1 branch. I think I had to do autoreconf or autoconf 
because my version of automake/autoconf were older than configure 
expected. Then a basic configure and make. It takes a long time to build….

I’ll try again on a different machine. I don’t want to mess up the 
version I have. I usually have a very hard time building gcl if the 
directory is not pristine.
