 The msgfmt command is required to build libpurple.  If it is installed
 on your system, ensure that it is in your path.  If it is not, install
 GNU gettext to continue.

+If you have msgfmt installed, but for some reason this error message

+configure again, like this:

+MSGFMT=/path/to/msgfmt ./configure ...
