Messages while installing gcr 3.20.0 on Mac OS X 10.6.8, Snow Leopard

[ballapete (Peter "Pete" Dyballa)]

While installing for the first this package, required by something else, I could read:

Please add the files
  codeset.m4 gettext.m4 glibc21.m4 iconv.m4 isc-posix.m4 lcmessage.m4
  progtest.m4
from the /opt/local/share/aclocal directory to your autoconf macro directory
or directly to your aclocal.m4 file.
You will also need config.guess and config.sub, which you can get from
ftp://ftp.gnu.org/pub/gnu/config/.

What does that mean? What should I perform? And when?

At the end another message was generated:

Note that '/opt/local/share' is not in the search path
set by the XDG_DATA_HOME and XDG_DATA_DIRS
environment variables, so applications may not
be able to find it until you set them. The
directories currently searched are:

- /opt/local/var/macports/home/.local/share
- /usr/local/share/
- /usr/share/

For which user should I set the environment variables XDG_DATA_HOME and XDG_DATA_DIRS? Or should I set them centrally in /etc/profile? And to which values? The pathname /opt/local/var/macports/home/.local/share does not exist on my Mac…

Nothing to do here. The configuration warnings quoted are a suggestion to the upstream developers to add these macro files to the tarball. In the meantime, although it's not apparent from this message, aclocal copies these files to aclocal.m4 as necessary during the (re)-configuration process.

The second message reported can also be ignored. gcr (as used in seahorse, for example) works for me as installed.
