*** /tmp/tmpJbaQ_x/bug_body
In Ubuntu, the attached patch was applied to achieve the following:

  * d/p/version-parse.patch: (LP: #935221) Use version->parse to compare
    installed augeas version to required minimum. 

Without the patch applied, the version check doesn't recognize 0.10.0 as 
greater than the required 0.9.0 version, as seen in the buildlog here:

https://launchpadlibrarian.net/87294645/buildlog_ubuntu-precise-i386.libconfig-augeas-perl_0.902-1_BUILDING.txt.gz

dh build
   dh_testdir
   dh_auto_configure
***
*** 'pkg-config' did find augeas version 0.10.0 but 
*** version 0.9.0 minimum is required
***
   dh_auto_build
   dh_auto_test

This causes the package to be empty.

Note that this isn't a problem in Debian yet, which hasn't updated to augeas 0.10.0.

See this snippet:

andreas at anubis:~/t$ cat test.pl
use version;

$version1 = "0.9.0";
$version2 = "0.10.0";

print "Using version->parse\n";
if (version->parse($version1) > version->parse($version2))
{
print "$version1 is greater than $version2\n";
}
else
{
print "$version1 is less than $version2\n";
}

print "Using >\n";
if ($version1 gt $version2)
{
print "$version1 is greater than $version2\n";
}
else
{
print "$version1 is less than $version2\n";
}
andreas at anubis:~/t$ perl test.pl
Using version->parse
0.9.0 is less than 0.10.0
Using gt
0.9.0 is greater than 0.10.0
andreas at anubis:~/t$

Thanks for considering the patch.

Cheers,
