Hi Santiago - back on: aclocal: error: too many loops aclocal: Please contact <bug-automake@gnu.org>. at /usr/share/automake-1.16/Automake/Channels.pm line 655.
I still don't know how to improve the error message, but in response to the same bug report with another package (#77395), I found that in the past, the error was related to older macros in the package tree overwriting newer macros found elsewhere, or redefining Autoconf macros. If you want to pursue it, you might read through https://debbugs.gnu.org/cgi/bugreport.cgi?bug=49901, which sounds likely to be the same problem, with some fixes and references. I'm going to try to merge your report into 77395 since they appear to be the same issue. --thanks, karl.
