yes - you need an executable for infocmp to build this.  It's mentioned
in this paragraph in the INSTALL file:

        By default, there are no entries on the fallback list.  After you
        have built the ncurses suite for the first time, you can change
        the list (the process needs infocmp(1)).  To do so, use the script
        MKfallback.sh.  A configure script option --with-fallbacks does this
        (it accepts a comma-separated list of the names you wish, and does
        not require a rebuild).

Normally fallbacks are used for embedded systems, and those generally do
not have development environments.  So that is not often a problem.  You
need infocmp because the fallbacks are built into the ncurses library,
which is built before infocmp (because infocmp is built using the ncurses
library).
