Make for Ruby 1.9.3 results in "cc1: out of memory allocating X bytes after a total of Y bytes"

I am unable to install RoR on a VPS running RedHat Linux with 512 MB.
When
I run “make” and “make install” I get the following output/error below.
What can I do to resolve this memory problem?

It appears I should have sufficient memory to install. I included the
results of “make” and “free” to show the failure as well as the
available
memory.

Thanks in advance!

You’ll definitely want to free up some RAM - 368M out of 512M used is
going
to seriously cramp the compilation process, especially without any swap.
What else is running on the VPS that’s eating up all that RAM?

The other process running on the VPS was the cPanel environment. This is
a
common domain management interface offered by many hosting providers.

I was able to get around this issue simply by upgrading my account to a
768
MB package. Although this did not solve the original question asked in
this
thread, it allowed me to move forward and get closer to releasing
working
software.

So to all those out there trying to install Ruby on Rails in VPS
environments, go straight for the 768 MB solution. That is unless you
can
figure out how to manage memory better. If you figure that out, please
post
here for others.
