Well, I'm not sure if pgsql-hackers is quite the right mailing list
for this (there's a plv8 mailing list), but because plv8 is probably
going to be so instrumental to many profitable uses I can help you
address it quickly, and maybe some other denizens of -hackers will
have some opinions, especially because this general problem is going
to surface more frequently as number of extensions mushroom.

Until a distribution/operating system integrator commits to packaging
some version of plv8 and/or v8, I recommend employing static linking
of plv8 to a self-downloaded libv8. This lets you handle multiple
versions of plv8 and libv8 on the same system (but different database
installs) and lets you get the latest and greatest v8s at-will.

Alternatively, you may be determined to get the plv8 build to work
with your OS of choice, even if they do not have packages. I think
that's a longer discussion that'd need to happen at a plv8 mailing
list.

In general, I think if there is to be a guideline for Postgres
extensions it should be to enable static linking of dependencies or
perhaps a more detailed guideline involving enabling self-contained
concurrent installs of dynamically linked extension dependencies. I
am currently in the depths of dependency hell involving some of the
GIS libraries and PostGIS and really, really wish I could do either of
these.

There is a relevant discussion here:
