Installation failed: gcc exited with exit code 4

Hi,

I tried to install Plone on ubuntu, but it failed. The log shows the following error:

Can anyone sugget a solution for this problem?

Thanks.

Probably a memory problem?
see python - lxml installation error ubuntu 14.04 (internal compiler error) - Stack Overflow

Thanks. Yes, it was a memory problem. I added a swap drive an the problem resolved.
