sox FAIL util: Unable to load LAME encoder library (libmp3lame).
sox FAIL formats: can't open output file `meiko_kaji-urami_bushi.mp3':
First of all, I do have libmp3lame0 installed. Secondly, I don't really
want this operation to do any reencoding.

Hello Michael,
a priori, I'm unable to reproduce the issue.
Can you rerun with "-V4" and attach the output to see if we get more
information?
I'm assuming that you have libmp3lame0 3.98.4-0.0 packaged by
Christian Marillat.
Please correct me if I'm wrong.
Cheers,
-Pascal

right, I have his package which contains /usr/lib/libmp3lame.so.0 and
/usr/lib/libmp3lame.so.0.0.0

Oh! This looks like it may be an upstream issue.
SoX looks for libmp3lame.so but not libmp3lame.so.0.
While it's only a symlink to so.0, the .so is "installed" by
libmp3lame-dev this if you install the latter, it should work.
That being said, having the dev package should not be required.
SoX dev guys: Under Debian and Fedora at least, the .so symlink is
created by the -dev or Devel packages respectively. So I wonder how
other applications using libltdl handle a situation like this. Do they
depend on the -dev/Devel package (which I'd like to avoid at all cost)
or do they workaround the issue by e.g. calling lt_dladvise_ext to get
the OS-specific extension and then look for libname.advised_ext*
before issuing an lt_dlopen on the found files...?
Chris, Doug, Robs, do you have thoughts on this?
Cheers,
-Pascal

I guess we only stressed this on windows were we've hit the problem
but solved it differently. It looks for both libmp3lame.dll/.so and
libmp3lame-0.dll/.so; "-0" be windows version of .so version #'s.
I couldn't really find any common solutions to this so I guess the
main solution would be to add libmp3lame.so.0 to the list of filenames
to search for. I think lt_dlopenext() can handle this full name.

at least here, lt_dlopenext() goes straight to attempting
libmp3lame.so.0.{la,so} when "libmp3lame.so.0" is specified.
I can't seem to find a way to modify the extensions it will attempt,
it does not seem to be accessible from the outside of ltdl.
lt_dlforeachfile seems to be total overkill for this and only returns
the filename without the extension anyway... (in my case it calls my
function with /usr/lib/libmp3lame while only
/usr/lib/libmp3lame{.so.0,.so.0.0.0} exist).
But ltdl does not seem to be designed for our purpose as there is no
other mechanism...
I could only fix this by using lt_dlopen() with a full filename
(appended extension myself with sprintf).
I'm to shy to share my ugly patch tho as it involves a fixed size char
array that can only be abused.
(The magic should happen in the lsx_open_dllibrary function of src/util.c).

Thanks for feedback on behavior.
I'm not up for re-implementing lt_dlopenext() at the moment although
that sounds like best way to go. I'm thinking as a short term fix we
could scan the filename for a ".". If found use lt_dlopen() and if
not use lt_dlopenext()?
Of course, still update all the various library lists to include an
exact .so name.
