Oh foo.

cd /proc/sys/kernel
echo 2048 >file-max
echo 4096 >inode-max

will up your file-max and inode-max, no compile required. 

I always put those commands in my /etc/rc.d/rc.local file on systems that
I know are going to be used heavily (e.g. at large schools where 40
teachers are going to jump online at once to post grades, calculate it
yourself, the Post Grades program accesses a half-dozen database tables
each of which is a file, each database table averages a half-dozen indexes
each of which is a file, we're talking 1680 files there plus the normal
overhead and normal usage...).
