Oh, bugger! That means that something is broken.
What is happening is that the Package stuff is trying to ascertain whether your
lyx.exe is running in its build tree (that location is hard coded). The expected
result (on your machine), of course, is no it's not running in its build tree.
That being the case, the Package stuff goes on to check that your lyx.exe has
been installed correctly.
Things worked fine on LyX 1.3.x. Since then, however, Lars moved over a bunch of
file and directory manipulation/checking utilities to use a library external to
LyX's sources (Boost). There's a change of semantics associated with this move.
The idiom is now:
if (exists(dir) && is_directory(dir))
...
Your bug report suggests a missing "exists(dir)"
Hope this is enough to help someone track the problem down...
