llvm 2.6-0ubuntu1 (powerpc binary) in ubuntu karmic

 The Low-Level Virtual Machine (LLVM) is a collection of libraries and
 tools that make it easy to build compilers, optimizers, Just-In-Time
 code generators, and many other compiler-related programs. LLVM
 uses a single, language-independent virtual instruction set both
 as an offline code representation (to communicate code between
 compiler phases and to run-time systems) and as the compiler internal
 representation (to analyze and transform programs). This persistent
 code representation allows a common set of sophisticated compiler
 techniques to be applied at compile-time, link-time, install-time,
 run-time, or "idle-time" (between program runs).
 .
 The strengths of the LLVM infrastructure are its extremely
 simple design (which makes it easy to understand and use),
 source-language independence, powerful mid-level optimizer, automated
 compiler debugging support, extensibility, and its stability and
 reliability. LLVM is currently being used to host a wide variety of
 academic research projects and commercial projects. LLVM includes C
 and C++ front-ends (based on GCC 4.0.1), a front-end for a Forth-like
 language (Stacker), a young scheme front-end, and Java support is
 in development. LLVM can generate code for X86, SparcV9, PowerPC,
 or it can emit C code.
