Gem installation fails when directory path contains spaces

Hi folks,

Sorry, bit of a dull one here, I'm experiencing an issue whereby I'm unable to install gpgme when my gem path contains a space. I'm very much a noob in ruby terms so I'm not entirely sure what's going on but it seems to be related specifically to this gem, as opposed to a general bundler/ rubygems isssue.

The following should hopefully demonstrate the problem:

#!/usr/bin/env bash

DIRECTORY_PATH="/tmp/directory with spaces in its path"
mkdir -p "${DIRECTORY_PATH}"
echo "Created directory: ${DIRECTORY_PATH}"

cd "${DIRECTORY_PATH}"
echo "entered directory ${DIRECTORY_PATH}"

echo "2.5.1" > .ruby-version
echo "Written .ruby-version file"

cat << EOF > Gemfile
source 'https://rubygems.org' do
  gem 'gpgme', '2.0.16'
end
EOF
echo "Written Gemfile"

bundle install --path .gems

For me, this results in the following error:

Fetching gpgme 2.0.16
Installing gpgme 2.0.16 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

    current directory: /tmp/directory with spaces in its path/.gems/ruby/2.5.0/gems/gpgme-2.0.16/ext/gpgme

************************************************************************
IMPORTANT!  gpgme gem uses locally built versions of required C libraries,
namely libgpg-error, libassuan, and gpgme.

If this is a concern for you and you want to use the system library
instead, abort this installation process and reinstall gpgme gem as
follows:

    gem install gpgme -- --use-system-libraries

Gem files will remain installed in /tmp/directory with spaces in its path/.gems/ruby/2.5.0/gems/gpgme-2.0.16 for inspection.
Results logged to /tmp/directory with spaces in its path/.gems/ruby/2.5.0/extensions/x86_64-linux/2.5.0-static/gpgme-2.0.16/gem_make.out

An error occurred while installing gpgme (2.0.16), and Bundler cannot continue.
Make sure that `gem install gpgme -v '2.0.16'` succeeds before bundling.

In Gemfile:
  gpgme

To my untrained eye it looks like spaces aren't being accommodated when the GCC command is being built e.g.

gcc: error: with: No such file or directory
gcc: error: spaces: No such file or directory
gcc: error: in: No such file or directory
gcc: error: its: No such file or directory
gcc: error: path/.gems/ruby/2.5.0/gems/gpgme-2.0.16/ports/x86_64-linux-gnu/libgpg-error/1.27/share/locale": No such file or directory

I have tried the same thing locally against a directory with no spaces in the path and it works fine, the unfortunate thing being I can't change the path on the particular system this is being deployed to.

Most grateful for any assistance / knowledge of any workarounds on this one.

Cheers,

Edd
