[Lazarus] Building trunk Lazarus with trunk FPC

[Mark Morgan Lloyd]

I know that this is not a supported combination, but I've just been 
trying to build trunk Lazarus (r43576) with trunk FPC (r26258) to see if 
I can work around a couple of recently-fixed issues. FPC trunk builds 
clean, and Lazarus (default configuration) builds with FPC 2.6.2.

On x86-Linux (Debian "Squeeze"), I notice a dependency on cairo-gobject, 
which only appears to have been added to typical distreaux recently. I 
presume that this is more of an FPC issue.

On SPARC-Linux (Debian "Lenny"), I get this:

..

..

Does anybody have any thoughts on this, or suggestions as to how I can 
get more useful debugging info?

I appreciate that neither of these OSes are particularly fresh, but I'd 
comment that Lenny in particular is a bit of a "sweet spot" as far as 
non-x86 platforms go: SPARC, some PPC and some ARM (and possibly other 
systems which I don't have here) suffer from fairly severe "bit rot" on 
later versions.
