Hi Adrian,

thank you for your time. This sounds a bit complicated for the newer

Currently i don't know where to start.
I was trying to build the old firefox52 and thunderbird52 which run on
NetBSD/Sparc64 from pkgsrc and manually. The thunderbird52 exists on debian
and the firefox package did skip 52 and was only released as a 50 with
error messages filling up the console. I can get them to build with pkgsrc
and manually but some patches seem to be missing to avoid bus errors in
libxul.so on debian.

Unfortunately i don't know yet how debian builds its own packages and where
to find the patches used in those builds, so that i could reproduce the
building of firefox50 and thunderbird52 to maybe learn something as a
starting point.
