Build failure in Ubuntu 15.04

[spiralgen]

I run:

./build_ocarina.sh -s -u
./build_ocarina.sh -b

I get the following:

I was able to get the build to proceed by commenting out:

Thanks for your report. Actually, Try_Help came from a later GNAT version. You may have more luck with GNAT GPL 2016 or GCC version above 5.2. Your work-around is OK, but you'll loose help from the CLI.
