libxul compilation problem

[Fernando Apesteguía]

Hi,

I have a ports version fetched on Oct 13th. I wanted to update all the
ports I have installed.
In order to do that I run:

swap_pager_getswapspace(16): failed
swap_pager_getswapspace(12): failed
swap_pager_getswapspace(16): failed
swap_pager_getswapspace(12): failed
swap_pager_getswapspace(16): failed
swap_pager_getswapspace(12): failed
...
...
swap_pager_getswapspace(3): failed
swap_pager_getswapspace(3): failed

The process being killed is cc1plus while compiling libxul. I'm
running a stock 8.1-RELEASE GENERIC kernel on amd64 platform.
The machine has 1Gb of physical memory and 256MB for swap (I have had
this setup for quite a long time and have always kept
my system up to date using the ports infrastructure without problems).

Do I need any special setup to compile this package? Maybe any systcl
vm.* should be tunned?

Thanks in advance.
