[BLISS ROMS Development] DoughMucker:
A progress update on building Bliss-x86...

I was able to manually install houdini by editing ~/blissos/p9.0/vendor/bliss_priv/setup.sh as follows:

#!/usr/bin/env bash

#CHANGED THESE
export SCRIPT_DIR=$PWD
export SOURCE_DIR=$PWD"/source"
export TARGET_DIR=$PWD"/proprietary"

export CHROMEOS_RECOVERY="chromeos_11151.33.0_nocturne_recovery_stable-channel_mp"
CHROMEOS_DOWNLOAD="$CHROMEOS_RECOVERY.bin.zip"
CHROMEOS_DOWNLOAD_URL="https://dl.google.com/dl/edgedl/chromeos/recovery/$CHROMEOS_DOWNLOAD"
CHROMEOS_DOWNLOAD_SHA256="f660e18709b023bf9a8ac198c3292cf037ecda3aa566281182d8e38fc0ce6c14"

#CHROMEOS_CHANNEL="canary"
#CHROMEOS_VERSION="11196.0.0"
#CHROMEOS_DOWNLOAD="chromeos_${CHROMEOS_VERSION}_eve_$CHROMEOS_CHANNEL-channel_full_mp.bin-6fc7a89e4795297c76e32385aa4fd5e5.signed"
#CHROMEOS_DOWNLOAD_URL="https://storage.googleapis.com/chromeos-releases-public/$CHROMEOS_CHANNEL-channel/$CHROMEOS_CHANNEL-channel/$CHROMEOS_VERSION/$CHROMEOS_DOWNLOAD"
#export CHROMEOS_DOWNLOAD_SHA256="db4a84069a38f950f6374065dfc905c26f26e8fc22abb6ea6b6bf1588aaa9335"

# Fail if an error occurs
set -e

function download {
file="$1"
url="$2"
sha256="$3 $file"

# Check if sha256sum matches local file
sha256sum -c <<< "$sha256" 2> /dev/null && return

# Download file
echo "Downloading $file..."
echo "$url"
curl -Lo $file "$url"

# Check again if new file matches md5sum
sha256sum -c <<< "$sha256" && return

# Remove invalid file
rm -f "$file"

# Report error
echo "Cannot download $file. Please try again later."
return 1
}

echo "Downloading files..."
#Already created these
#mkdir source && mkdir proprietary
cd "$SOURCE_DIR"

download "$CHROMEOS_DOWNLOAD" "$CHROMEOS_DOWNLOAD_URL" "$CHROMEOS_DOWNLOAD_SHA256"

echo "Deleting old files"
#Didn't need these
#rm -rf "$TARGET_DIR"
#mkdir "$TARGET_DIR"

export TEMP_DIR=`mktemp -d`
cd "$TEMP_DIR"

echo "Processing $CHROMEOS_DOWNLOAD"
"$SCRIPT_DIR/extract.chromeos.sh" "$SOURCE_DIR/$CHROMEOS_DOWNLOAD"

rm -r "$TEMP_DIR"
echo "Done"

then I ran:

bash ~/blissos/p9.0/vendor/bliss_priv/setup.sh

and houdini installed.

Now when I run bash build-x86.sh -r android_x86_64-user, I get the same error as someone earlier posted:
