I’m trying to build Julia from source using the Intel Math Kernel Library. I’ve done this successfully on Fedora, but I’m hitting a snag when building on Gentoo. Here’s what I’ve done:

- `git clone git://github.com/JuliaLang/julia.git`

- `cd julia`

- `git checkout v1.1.0`

create a Make.user file containing:

```
USE_INTEL_MKL=1
MARCH=native

```

- `make`

This results in:

```julia
find: ‘/home/zaen/repos/julia/usr/share/julia/stdlib/v1.1/*/src’: No such file or directory
/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -lmkl_rt
/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -lmkl_rt
collect2: error: ld returned 1 exit status
make[1]: *** [/home/zaen/repos/julia/deps/suitesparse.mk:52: /home/zaen/repos/julia/usr/manifest/suitesparse] Error 1
make: *** [Makefile:57: julia-deps] Error 2

```

When I check `usr/share/julia/stdlib` I can see that it’s empty. On my Fedora installation it’s not. What would cause this?

This directory is apparently not supposed to contain anything before Julia finishes the first build. Gentoo seems to ignore the LD\_LIBRARY\_PATH variable, but adding `LDFLAGS="-L/opt/intel/compilers_and_libraries/linux/mkl/lib/intel64"` to Make.user allowed me to build successfully.
