Ah, didn't know that :)

Well, it seems the llvm include path is missing:

[...]

I do see the correct values in mono/mini/Makefile though:

LLVM_CONFIG = /home/melis/llvm/bin/llvm-config
LLVM_CXXFLAGS = -I/home/melis/llvm/include  -D_DEBUG -D_GNU_SOURCE
-D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS -O2 -fomit-frame-pointer
-fPIC
LLVM_LDFLAGS = -L/home/melis/llvm/lib  -lpthread -lffi -ldl -lm
LLVM_LIBS = -L/home/melis/llvm/lib  -lpthread -lffi -ldl -lm 
-lLLVMX86CodeGen -lLLVMX86Info -lLLVMX86Disassembler -lLLVMSelectionDAG

-lLLVMScalarOpts -lLLVMTransformUtils -lLLVMipa -lLLVMAnalysis
-lLLVMTarget -lLLVMMC -lLLVMBitWriter -lLLVMCore -lLLVMSupport
-lLLVMSystem -lstdc++

A bug in the build system?
