What's the simplest way to get a fresh copy of the source code for the system

Hi,

My churches web server is having problems compiling world for FreeBSD  
7.0-p10 (I believe I just did the csup last night). It gets to this point  
and then stops with this error:

touch gtype-desc.h
touch: No such file or directory

A little history for what's going on; the server was not responding at all  
so I took it home to diagnose (it was at a friends house, where it's  
hosted). I turned it on and it booted up ok for me, which was a little odd  
because he told me that it wasn't doing "anything." So, I began looking the  
system over. Within 10 minutes the system became slow and was rather  
unresponsive to things. For example, saves while running vim took 20  
seconds or so. Within a few minutes the kernel panicked and I had to reboot.

Before the panic I noticed that there were some background file system  
checks going. So, since it was rebooting anyway I went into single user  
mode and performed fsck on all of the partitions (except the root, that was  
marked as clean). There were many problems fixed especially on the /usr  
partition. I'm betting that this missing file, gtype-desc.h, happens to  
have been one of the many problems fixed.

At any rate, after running the file system checks I rebooted normally and  
everything appears to be fine. I then updated the system and kernel source  
code and that's when I found this problem. The kernel built ok and I've had  
the system running for up to 2 hours since fixing the file systems without  
incident. It's apparently corrupted file systems rather than hardware.  
Never the less, I will be turning up what smartd is monitoring because I do  
have it running and received no e-mail about hard drive problems.

So, basically, the question for everyone here is, what's the simplest way  
to get a fresh source code tree so that I can build the world applications?

Thanks,
Andy
