错误建筑PostgreSQL的宝石与`budle install` [Ubuntu的10.04，红宝石EE]

Question

我在Ubuntu 10.04安装Ruby企业版作为默认的Ruby解释：

ruby 1.8.7 (2010-12-23 patchlevel 330) [i686-linux], MBARI 0x8770, Ruby Enterprise Edition 2011.01 

如果我sudo gem install pg，创业板安装成功。

但withing我的Rails应用程序，bundle install挂断这样的：

这是内存缺乏对的一问题与OpenVZ的VPS。

只有256 MB的RAM，OpenVZ不提供交换空间。所以剧本挂断了。
