"make distclean" is the right thing to do here. Because new source has 
been downloaded, the Makefile's have to be changed accordingly.

I wouldn't think so.

The HSL is indeed optional if you download Mumps. If you do obtain the 
source code for HSL, however, Couenne will attempt to configure and 
compile the code.

This might happen from time to time. In some cases I found it useful to 
run BuildTools/run_autotools from the base directory, and then configure 
again from the build/ directory.

I agree, although sometimes it is the only way.

Hope this helps.

Best,
