filesystem full error

[Dave Webster]

Hi,
I'm trying to: pkg_add -r openoffice and I get the following:

/var: write failed, filesystem is full
mkdir: /var/db/pkg/ORBit-0.5.17_2: No space left on device
pkg_add: can't record package infor '/var/db/pkg/ORBit-0.5.17_2', you're
on your own!

That last part is particularily chilling - if I'm on my own, I'm hooped!

Here's the result of df -h:
 
Filesystem     Size    Used   Avail Capacity  Mounted on
/dev/ad0s1a    248M     93M    135M    41%    /

linprocfs      4.0K    4.0K      0B   100%    /usr/compat/linux/proc

Any suggestions on what I should do?
thanx in advance,
Dave
