+	  for all kinds of public key directories. GnuPG, also known
+	  as GPG, is a command line tool with features for easy

+	  gpgv2 is an OpenPGP signature verification tool.
+
+	  This program is actually a stripped-down version of gpg
+	  which is only able to check signatures. It is somewhat
+	  smaller than the fully-blown gpg and uses a different (and
+	  simpler) way to check that the public keys used to make the
+	  signature are valid. There are no configuration files and
+	  only a few options are implemented.

+Fix usage of PTH_CONFIG to work with pthsem
+
+The pthsem re-implement of pth provides a compatibility layer for pth,
+but its pth-config script behaves slightly differently than the
+original one when reporting the version number. This patch to gnupg2's
+configure script adjusts the version checking to support this
+difference, since Buildroot uses pth-config from pthsem.
+
+We patch directly the configure script, because triggering the entire
+autoreconf dance for just a one byte change in the configure script
+seems a bit silly.
