According to http://hugin.sourceforge.net :
[Hugin is] an easy to use cross-platform panoramic imaging toolchain based on Panorama Tools.
"libpano", listed by mason, contains the so-called "Panorama Tools" and "hugin" indeed depends on them (wheras Pandora, the GIMP plugin, does not). If those are the tools you are referring to, then Hugin is probably what you want.
