you should find in the config.log file generated by the configure script 
the reason why the configure script failed to activate public key cipher 
support.

there is no risk here as the version check is done by gpgme itself by 
mean of gpgme_check_version() function [1]

and here the check is done at run time not at compilation time, so it's 
unlikely the cause of the problem.

Sure. Double check you have all the prerequisites here:

http://dar.linux.free.fr/doc/from_sources.html

For libraries, you should have installed also the included files. Debian 
makes sperarated packages for them, those ending with *-dev, don't know 
about Arch. Anyway, this should show in the config.log generated file
