Bug#834744: xmlgraphics-commons: FTBFS (missing build-depends on gnupg)

[Santiago Vila]

Package: src:xmlgraphics-commons
Version: 2.1-1
Severity: serious
Tags: patch

Dear maintainer:

I tried to build this package with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

--------------------------------------------------------------------------------
[...]
BUILD FAILED
/<<PKGBUILDDIR>>/build.xml:620: The following error occurred while executing this line:
/<<PKGBUILDDIR>>/build.xml:591: Execute failed: java.io.IOException: Cannot run program "gpg" (in directory "/<<PKGBUILDDIR>>"): error=2, No such file or directory
--------------------------------------------------------------------------------

The gnupg package is not essential. Therefore, whenever a package
requires it for building there should be a build-dependency on it.

Trivial (but untested) patch below.

Thanks.
