[Mono-list] Mono can't find libMonoPosixHelper.so

Thanks for the info Robert.

When I read the details of the aforementioned bug, and saw the suggested
workaround, I thought that meant the LD_LIBRARY_PATH solution was not the
way it was designed to work.

So, just to be perfectly clear, does this mean that changing LD_LIBRARY_PATH
(and all the other env vars mentioned in that article, I suppose) is the
'correct' way to install Mono in a non-standard location?  Have I just been
lucky not to encounter any other problems so far without that setting?

I am not familiar with the /etc/ld.so.conf setup but it sounds like a nicer
way to split things out.  I will take a look.

Thanks again.
