Bruce, I don't think this is packaging specific. I believe it's based on how the Processing toolbox in QGIS is coded. I think you should talk to the author Victor on the QGIS dev mailing list. I actually have a similar gripe that SAGA algorithms convert everything to shp before using, which means I can't use my big 4 GB+ postgis data sets with it.
