Hi Sugar developers (and Mike), Mike Hommey maintains Debian packaging of xulrunner.
I asked him about the use of hardcoded rpath in Hulahop, which is generally a bad idea and its use is being hunted down in Debian.
He had a look at the Hulahop code and suggestions for improvements. He is kindly offering to help with this if necessary.
Please read below - and please cc him on responses (no need to cc me, I am subscribed to this list):

It was Wed May 7 2008 - is that a long time in this context? It was at the time xulrunner 1.9 was introduced to Debian. Now that I look at the VCS history of python-hulahop, it might actually be that it was not following your instructions but fumbled on my own (I added chrpath and removed it again later same day, with no reference to that web page I seem to recall reading from you). Hm. >>Now ftpmasters auto-rejects python.hulahop based on a lintian check >>discovering that rpath, and I want to do the sane thing and >>double-checking that the rpath really should be preserved, as part >>of hiding that lintian warning. >> >>So question is: Do xulrunner need rpath preserved?

I tried now to strip the rpath using chrpath, and immediately the code stops working, spewing the following error: ImportError: libxul.so: kan ikke åbne delt objektfil: Ingen sådan fil eller filkatalog ...translated from danish to english, it says something like this: ImportError: libxul.so: cannot open shared object file: No such file or directory Maybe relevant: I added +LDFLAGS += -L/usr/lib/xulrunner-1.9 to the build routines, as fix for bug#494225.Which just does nothing, since it is /usr/lib/xulrunner-1.9.1, now.Could I persuade you to help investigate this issue - even if perhaps not rooted in your package but some bug in Hulahop itself?It seems to me the root of the problem is that python-hulahop is using the linked glue instead of the standalone glue. I also wonder why it's not using pyxpcom for xpcom initialization, instead of having its own stuff in hulahop.cpp, though I don't really know what pyxpcom permits exactly. Anyways, it seems to me the XRE_InitEmbedding call should be replaced by the following sequence: GRE_GetGREPathWithProperties XPCOMGlueStartup XPCOMGlueLoadXULFunctions XRE_InitEmbedding If you need assistance with these, please bug me.
