I wrote gattrib some time ago.  It is kind of limited in what it can
do, and I suspect you can't use it on components which don't have the
proper set of attributes that electrical components have in gschem.

What I do is this:  I use gattrib to read in my schematic components,
then do file->export csv.  Then I read the CSV file into oocalc (or
your favorite spreadsheet program), and add the other BOM components
there.  I put unit costs into my component's attributes, so I can also
compute a BOM cost using oocalc.  In general, I use oocalc to manage
my entire BOM, and gattrib to manage and update the attributes of my
schematic components only.

I realize that you can't use this flow to add non-electronic
components back into your schematic.  However, to hold those
non-electronic components in gschem/gattrib, you need to create a full
symbol with the right set of attributes (at least a DEVICE and REFDES
attribute, IIRC). This is a PITA, so I don't generally do it for
random stuff like fasteners.  YMMV.

I know DJ has a similar work flow, but he uses a script he wrote (I
belive) which reads .sch files and creates a .csv directly.  You might
look at his scripts on gedasymbols.org for that script.
