Hi Ingo.

My AC_LIB_PREPARE_PREFIX is at /usr/share/gettext/m4/lib-prefix.m4 ,
which comes with the gettext package.  Which was already installed.

I still get the same error, when compiling pinentry from the official
tarball:

```
$ wget https://www.gnupg.org/ftp/gcrypt/pinentry/pinentry-1.3.1.tar.bz2
(...)

$ tar xf pinentry-1.3.1.tar.bz2 

$ cd pinentry-1.3.1/

$ ./autogen.sh

Ingo, can you try to see if you also get this error, and tell me your
result?

Can someone tell me if is just my system that gets this error?
