since 1.0.4, gnupg comes with a tool named gpgv which does exactly
what you want.  It is smaller than gpg but still quite large.

If you need a really slim verification tool, have a look at SFSV
(ftp://ftp.guug.de/pub/members/wkoch/crypto/).  This is a tool to
OpenPGP sign an ELF file and embed the signature in the ELF file.
The library part then can be used by the ELF loader to check that
signature.  It is not very fast but the memory footprint is about
18k. useful for embedded systems to check.  It is GPLed; if you have
problems with this, please contact me privately.
