Well, the fonts exist anyhow. And they existed before the upgrade too.

Luckily, I've been able to determine that the upgrade from Solaris
10u10 to Solaris 10u11 was the start of this problem (had an old BE
around and I booted back and everything is fine). That doesn't explain
it though.

I recompiled showgraph.cgi too. No real difference. Maybe a little
faster, but still runs for 25 seconds just to make one graph.
