Not being derogatory here, but you appear far short of a developer in
missing the relatively low hanging fruit here.

-l flags to gcc are to include libraries. So take the -lndbm error
message and go look for libndbm. Google has a lot of results for it.

If your script was truly simple, I doubt you would have a high load
average. Could it be that you are really just memory starved and your
load average is skyrocketing due to swap thrashing? I could see 100 perl
interpreters causing a large memory usage problem, but not necessarily a
high cpu usage unless they are doing something very busy.

Why not put those values into a variable that can be queried by the app.
Well actually, they are already in variables, why don't you just go use
the functions to look at the named variables?
As far as perl and fast-agi, it is modeled after the fastcgi interfaces.
You might do well to go learn how fastcgi works with perl and determine
if you feel like continuing that route. I'm sure there is decent
documentation on fastcgi and perl available to either move you forward
or scare you away from it.
