Hi Thomas,
Sorry I only saw your response to this email now. Clearly I messed up
badly when building this before sending this patch, apologies.
Much of the feedback below is already done, the rest I will sort out
before sending a v2.
( BTW I was trying to reuse a system daemon script from WVIEW - clearly
a bad idea, I will write one from scratch ).

The daemon have a dependency on a webserver.
It uses apache + php to generate rolling graphs.
AUTOTOOLs checks for them as I remember.

Let me look into that one, it may not be accurate.

Apologies I thought I had, I clearly messed up - I usually do a 'rm -rf
output'.

radlib patch is in v5 on the BL mailing list.

I will look into this, I am pretty sure it is required. I will confirm.

Yes - this is the same mess that there was radlib, have had to make
similar changes there.

Thanks Thomas - apologies for the mess.
