help-links.sh not found by help.start() -- do I need to recompile?

[snip]

AFAIK, the approach of running R from within the build location is 
fully valid as it is noted at the end of section "2.1 Simple 
compilation", just above the cited one:
  

Yes, but then it is not "actually installed".

"... Note: you do not need to install R: you can run it from where it 
was built."
  

You can, but note that it doesn't say that you can move the build 
location afterwards, and in fact, you can not, because of the 
non-relative pathnames.

Actually, I have used R for a long time without any (apparent) problems 
being "installed" this way. I just changed the mentioned variables 
manually, and everything was running just fine -- until I needed to 
check the HTML help recently. Therefore I thought that I've missed to 
fix some config-file in an analogous maner to solve the problem with the 
script that wasn't found by the system.

I assume that I have to recompile (something that I was hoping to avoid 
due to the rather decent system I use currently) to get this issue 
fixed. Am I right?
