Reference found where even-sized list expected

[Pozsar Balazs]

hi again,

I get this warning:
Reference found where even-sized list expected at ./n.pl line 94.

when running my script, and i don't understand what does it mean.
Please explain. Here are the relevant lines:

94:     my %args = {
95:         descriptor  =>      "/usr/lib/nitro/all.xml",
96:         build       =>      {
97:                 cleanup     =>      1,
98:                 bindir      =>      "$origwd/binaries"
99:         }
100:    };


Thanks,
Balazs Pozsar.
