I've noticed the difference myself, ETIP_NEEDS_MATH_H is #defined as 0
when building in pbuilder but 1 when building on my normal system. The
obj/config.log file in the pbuilder build reveals a problem:

Since we build out of tree, the correct include directory would have
been /tmp/buildd/ncurses-5.9/obj/include rather than
/tmp/buildd/ncurses-5.9/include.
When building on my normal system, this problem is hidden because
libncurses5-dev is installed, and so the ncurses_dll.h copy in
/usr/include is used:
