Yes, this is what I meant. It looks like the config is missing the 
LLVM-3.0 shared object. Do you use LLVM-3.0? That is, it does not look 
like a conflict but like something missing. You may also post your 
llvm-base.buildinfo.in file. My one has this content:

llvm-git> cat base/llvm-base.buildinfo.in
cpp-options: -DTARGET=@llvm_target@
cc-options: @llvm_cppflags@
ghc-options: -pgml @CXX@
extra-libraries: LLVM-3.0 stdc++
extra-lib-dirs: @llvm_extra_libdirs@
ld-options: @llvm_ldoptions@
include-dirs: @llvm_includedir@

(I have locally moved @llvm_cppflags@ from cpp-options to cc-options.)

The critical lines in my llvm-base....conf are:

extra-libraries: LLVM-3.0 stdc++
extra-ghci-libraries:
ld-options: /usr/lib/llvm-3.0/lib/libLLVMXCoreCodeGen.a
             /usr/lib/llvm-3.0/lib/libLLVMTableGen.a
             /usr/lib/llvm-3.0/lib/libLLVMSystemZCodeGen.a
             ...
