Short answer: upgrade your gettext package to 0.10.38 or above.

Long answer: This is a bit more complicated. The whole gettext stuff
is divided into the two parts: functions(dcgettext and co) and
binaries(xgettext and co). Note that gettext and ngettext are both
functions and binaries.

The function part is included in the glibc. If you don't have glibc or
the glibc hasn't the correct version you can the use the functions
which came with freeciv (which are of version 0.10.38).

The binaries for gettext 0.10.38 aren't included in freeciv (which is
annoying but no other project ships them).

The recently introduced PL_ macro uses the plural format and this
format is only implemented in gettext 0.10.38 or above. So you can use
--with-included-gettext to get the functions but have to provide
0.10.38 binaries.
