Greetings!

This might just belong over in the bug tracker bug I figured I should start here.  I'm trying to build some of the 14.0 appliances and have been successful with a few (core, LAMP) but I'm running into problems with etherpad.  TL;DR the install script for node.js seems to be broken (yes, I did do the git pull in common).  My attempt to fix it is below but etherpad-lite eventually complains that it's not the right version of node.js

It does okay until it starts running the nodejs-install common script.  Then I get this:

fab-chroot build/root.patched --script /turnkey/fab/common/conf/nodejs-install
+ SRC=/usr/local/src
+ dl http://nodejs.org/dist/latest/SHASUMS.txt /usr/local/src
+ '[' http://127.0.0.1:8124 ']'

+ cd /usr/local/src

/usr/share/fab/product.mk:476: recipe for target 'build/stamps/root.patched' failed
make: *** [build/stamps/root.patched] Error 22

I've tried exploring things a little bit.  A quick examination of 'nodejs.org/dist/latest' shows that in fact SHASUMS.txt does not exist.  There is a file called SHASUMS256.txt so I tried messing with that, edited the nodejs-install script to get it to grab the sha256 file, little mangling of the regex to get the latest tarball (there's two now, .gz and .xz so I had to pick one), hoping that would be enough.

#!/bin/bash -ex

SRC=/usr/local/src

dl() {
    [ "$FAB_HTTP_PROXY" ] && PROXY="--proxy $FAB_HTTP_PROXY"
    cd $2; curl -L -f -O $PROXY $1; cd -
}

dl http://nodejs.org/dist/latest/SHASUMS256.txt $SRC

TARBALL_RE="linux-x${FAB_ARCH: -2:2}.*gz"
TARBALL=$(grep $TARBALL_RE $SRC/SHASUMS256.txt | cut -d " " -f 3)
dl http://nodejs.org/dist/latest/${TARBALL} $SRC

grep $TARBALL $SRC/SHASUMS256.txt > $SRC/$TARBALL.sha1
cd $SRC
sha256sum -c $TARBALL.sha1
rm SHASUMS256.txt $TARBALL.sha1

tar -zxf $SRC/$TARBALL -C $SRC
rm $SRC/$TARBALL
ln -s $SRC/node-v* $SRC/node

for f in $(ls $SRC/node/bin); do
    ln -s $SRC/node/bin/$f /usr/local/bin/$f
done

# npm completion
npm completion > /etc/skel/.bashrc.d/npm
chmod +x /etc/skel/.bashrc.d/npm
cp /etc/skel/.bashrc.d/npm /root/.bashrc.d/npm

This gets it past that problem but, not surprisingly, etherpad is still unhappy.  I eventually get this error when it tries to retrieve and install etherpad-lite and am not sure how to proceed:

You're running a wrong version of node, or io.js is not installed. You're using v4.1.0, we need v0.10.x, v0.11.x or v0.12.x

Basically, node.js is not installed right (or is not the right version).  Those version numbers are so drastically different I'm guessing something is fundamentally effed up here but I don't know anything about node.js or etherpad-lite's internals so I'm at a loss.  The spreadsheet indicates that the 14.0 etherpad appliance has made it through QA already (I think) so I was suprised to run into this.  I'm also guessing that node.js is a key part of other appliances so this probably needs some attention from someone that knows more than me!

Thanks!
