BuildRoot:      %{_tmppath}/%{name}-%{version}-%{release}-root-%(%{__id_u} -n)

# XXX Building this rpm requires that bundle is available on the path of the user
# that is running rpmbuild. But I'm not sure how to require that there is a 
# bundle in the path. 
#BuildRequires: /usr/bin/bundle
# XXX Also require gem on the PATH
# BuildRequires: /usr/bin/gem

# XXX Note that you might not require all the below. It will depend on what your gems require to build.

# From docs: http://nokogiri.org/tutorials/installing_nokogiri.html
# and: https://github.com/thoughtbot/capybara-webkit/wiki/Installing-QT
# which hinted that I should look for something like qt webkit devel ...
BuildRequires: libxml2 gcc ruby-devel libxml2-devel libxslt libxslt-devel
# for...I forgot to record what gem requires this to build... 
BuildRequires: qt-devel qtwebkit-devel
# for curb
BuildRequires: libcurl-devel
# for sqlite3
BuildRequires:  sqlite-devel
# ^^ There may be more requirements above for building on a new dev/rpmbuild env

# XXX Remove if not using apache/passenger/mysql
# Assuming will run via passenger + apache
Requires: mod_passenger, httpd
# And use mysql as the db
Requires: mysql-server

# In order to rotate the logs
Requires: logrotate

# What repository to pull the actual code from
# (assuming git here, you'll need to change for svn or hg)

	# bundler, so it would seem to me to be required. So, I used gem to install
	# bundler after bundle deployment. :) And the app then works under passenger.
