I only remembered that I had to upgrade the compiler. I checked which
version I had before and it was 3.3 and 3.4.3, so no wonder I needed
to upgrade. (The version 4.6 reported by Karl might just as well mean
that there was some weird bug in the gcc 4.5 that he tried to use.
Pure speculation though.)

LuaJIT seems to have different requirements for different platforms:
http://luajit.org/install.html. ICU is also a bit picky about compiler
version. There is some chance that even gcc 4.1 works on some
configurations, but independent of that the point still stands:
default compiler might not suffice. Using an older or newer compiler
is "allowed" as long as sources can be compiled. Using the latest
linux distribution on the other hand is not acceptable.

It might be worth checking whether using an older compiler can solve this issue.
