I don't mind if static linking is an option. (We will keep using

Ditto for soname versioning.

Yes, it's a dlopen-type thing. But it's about to go away because we're
about to remove the LLVM dependency (see the recent topics on B3).

Yes, this is an annoying bug. If it's only needed for libllvmForJSC,
then hopefully the problem is about to go away. :)

Maybe we should lower this requirement.
If you remove the version checks and build with
-DENABLE_DATABASE_PROCESS=OFF -DENABLE_INDEXED_DATABASE=OFF it will
work. See for an example:
Actually, it's possible that database process would work with newer
versions of GCC 4.8, but we haven't tested. 4.8.1 is almost certainly
If you're just building JSC, you can safely remove the version checks
