            2015-07-09 io.js v2.3.4 Release

            Notable changes

            * openssl: Upgrade to 1.0.2d, fixes CVE-2015-1793 (Alternate Chains
            Certificate Forgery).

configure with

    ./configure \
    --prefix=/usr/local/io.js \
     --dest-cpu=x64 \
     --dest-os=linux \
    --shared-openssl \
    --shared-zlib

is OK.

and never exits the script ... just sits here indefinitely

OTOH, a standard build, with

    make -C out BUILDTYPE=Release V=1 -j4
    make install

completes without error
