I was wrong, there is a version check also in the configure script for 
gpgme. This comes with the AM_PATH_GPGME macro used in dar/libdar 
configure.ac file.

The "WARNING:*" line shows because the macro did not pass.

I'd be interested in the following output:

	grep GPGME config.log

Could you check also you do not have an old gpgme.h header file 
somewhere? This should help.
	
	find /usr -type f -name "gpgme.h" -ls

Last track, you can add the --with-gpgme-prefix=PFX option to configure
to force the path to where gpgme has been installed: For example:

	./configure --with-gpgme-prefix=/usr/local  ... other options...

Interesting...

Well, if there is one AC_CHECK_LIB for gpgme in the dar's configure.ac 
file, it comes in consideration only once and if AM_PATH_GPGME 
succeeded, and in no case its failure is problematic. Not likely to be 
the same problem here as the bug report you mentioned.

However the report underlines that the AM_PATH_GPGME relies on 
gpgme-config utility. Do you have it in your PATH?

if so, what's the output of

	gpgme-config --version

and

	gpgme-config --print-lang

OK, thanks for the info.
