Build R with Intel Compiler

I am trying to build R with an Intel Compiler (14.0.3). Has anyone before done it and could give me a hint for the configuration?
I am sourcing the compilervars.sh for Intel and then configure R with
./R-3.0.2/configure OBJC="clang" --enable-R-framework=/usr/local/R/R-intel --x-includes=/usr/X11/include/ --x-libraries=/usr/X11/lib/ --enable-memory-profiling --with-blas="$MKL" --with-lapack
Further Variables are:
CFLAGS=?-O3 -ipo -openmp -xHost?
CXXFLAGS=?-O3 -ipo -openmp -xHost?
MKL=?-lmkl_gf_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread?!
I get always the same error:
/opt/intel/composer_xe_2013_sp1.1.103/bin/intel64/icc -std=gnu99 -I../../../R-3.0.2/src/extra/zlib -I../../../R-3.0.2/src/extra/bzip2 -I../../../R-3.0.2/src/extra/pcre -I../../../R-3.0.2/src/extra -I../../../R-3.0.2/src/extra/xz/api -I. -I../../src/include -I../../../R-3.0.2/src/include -I/usr/local/include -DHAVE_CONFIG_H -fPIC -O3 -ipo -openmp -xHost -c ../../../R-3.0.2/src/main/Rmain.c -o Rmain.o

Any clue what this could be?
The above certainly won't work, because you're missing linker flags - I'm pretty sure that you must use -openmp in the linker for it to work, I'm not sure about -ipo -- but doesn't R detect all those automatically? I don't think you should put them in manually. The actual error comes from missing libguide link flags, but they may be implicit if you fix the other problem. Cheers, S
