description         A high-performance dynamic programming language for technical computing
long_description    Julia is a high-level, high-performance dynamic programming language \
                    for technical computing, with syntax that is familiar to users of other \
                    technical computing environments. It provides a sophisticated compiler, \
                    distributed parallel execution, numerical accuracy, and an extensive \
                    mathematical function library. The library, mostly written in Julia \
                    itself, also integrates mature, best-of-breed C and Fortran libraries \
                    for linear algebra, random number generation, FFTs, and string processing.\
                    \n\nIf you want the development version instead of the newest version at the time \
                    of the last update of the Portfile, you can use the variant +latest, or build \
                    from source directly by using the build script in contrib. \
                    (typically, `git clone git://github.com/JuliaLang/julia.git\; \
                    \nLD_LIBRARY_PATH=${prefix}/lib:\${LD_LIBRARY_FLAG}\ && \
                    make -C julia/contrib -f macports.make PREFIX=${prefix}`)

    puts ${julia_script} "${prefix}/share/julia/julia"
    close ${julia_script}
}

This hasn't been updated in a while, so parts are almost certainly out-of-date (such as the use of USE_DEBIAN=1 instead of USE_SYSTEM_X=1). Additionally, I think the post-destroot script can be replaced by adding a LDFLAG that adds an rpath location of ${prefix}/lib to the binary
