Going back to 2.4.5 On Mac OS X

[Walter Hofmeister]

I've been testing the 2.5 series a bit and the new self contained packages
offered by the Development Team. This is great progress. I have had some
font and spacing issues with the 2.5.2x versions that I have tried. The last
one tested for me was the latest 2.5.27 package which did seem to solve the
font problems but the bar lines are still very thick. On my system, the self
contained package does not quit automatically. After the file is compiled,
it switches to viewing the file in Adobe Acrobat Reader. In order to quit, I
then have to switch to the Lilypond application and quit it. Could this be
automated? I have noticed that you simply cannot drag another file to the
application that is already open. Also all of the resulting output is placed
on my already polluted desktop. Is it possible to have the output placed in
the directory where the source file (.ly) was? I also got the impression
that the this application can be run from the terminal, but the information
on how to accomplish this was not sufficient that I could get it to work
(how to get the script file to run). Point and click also does not do
anything (the line number and position on the line are displayed in Acrobat
Reader though). Is this still a feature in progress or is there something
that might be causing a problem on my system? I do think that this is a very
positive approach to packaging Lilypond.
    I would like to be able to go back to the 2.4.5 version that I have
built as I have some things that I need predictable results for. When
re-installing v.2.4.5 on Mac OS X.3.4, I get the following when running a
file through Lilypond:

GNU LilyPond 2.4.5

There is a .pdf file produced, but is is blank. Can anyone tell me what need
to be fixed? Thanks a bunch.
