The aqbanking configure checks for the existence of the xgettext and msgfmt binaries to enable gettext, both which are not available on OS X by default AFAIK, that's why I appended `gettext.bin` to `PATH`

Unfortunately without `PKG_CONFIG` and `PKG_CONFIG_LIBDIR` other dependencies such as libxml, ktoblzcheck are not found by configure either.

I've tried many things in order to get this to work :wink: and appreciate any feedback to improve the formula.
