There isn't one. Even considering "standard packages", different Linux

/In/ /general/, you can rely on /usr/local/bin being on your path, or
it's safe to add it. So basically, you can install both FPC and Lazarus
wherever you want, and put symlinks in /usr/local/bin for the programs
you need most.
Thank you so much!
This last item clarified a lot of what has been going on in my RPi....
We're wandering away from Lazarus towards more general areas, but
craving the list managers' indulgence for a few moments...
Hint: when you're setting up a symlink, the order of the parameters is
as though you're doing a copy.
So a copy is like this:
$ cp actual_file copy_of_file
a hard link is like this:
$ ln actual_file hard_link
and a symlink (symbolic link) is ordered the same:
$ ln -s actual_file symbolic_link
Most operations on symbolic_link are now transparently redirected to
actual_file. I know for a fact that I am not the only person who gets
the order wrong on occasion, and I'd also add that you need to be
careful with relative vs absolute paths: if in doubt do something like
$ ln -s /usr/local/share/lazarus-trunk/lazarus /usr/local/bin/lazarus
rather than trying to cut corners.
I went into the/usr/local/bin directory and made a ls -la to see what
if any symlinks are there. Surprise! I found several dead symlinks:
..
All of these are pointing to the erroneous root installation I did as
root! They were probably put there my the make install command I
issued as part of the tutorial but did not do manually after getting
lazarus into the Pi home dir.....
But also see warnings above. BTDT.
But them being here explains how the Jessie start menu got screwed up
as well, because in the menu definitions were only things like
"startlazarus %f" without any path specifier at all.
Note also that whatever desktop software you're running (OpenBox, LXDE
etc.) will expand that %f to a filename, if given one as a parameter.
This isn't well documented, but is completely distinct from any shell
(environment) variables being expanded.
One can just change the symlink and keep everythying else like the
Menu entries....
That's right, but as I said you can also go via a (shell) script if you
need something fancier.
