Comment (by guibou):

 This `Dockerfile` shows that indeed the problem does not appear on a
 "normal" system:

 {{{
 FROM ubuntu:latest

 RUN apt-get update
 RUN apt-get install -y wget
 RUN wget -qO- https://get.haskellstack.org/ | sh
 RUN stack setup
 RUN apt-get install -y libgsl23
 RUN apt-get install -y libblas-dev liblapack-dev
 RUN apt-get install -y pkg-config
 RUN stack install vector

 RUN stack install hmatrix-gsl
 COPY Foo.hs /root/Foo.hs
 RUN stack ghc -- -package hmatrix-gsl -fexternal-interpreter /root/Foo.hs
