Created a SFourge account, but it won't let me logon ("no group_id"?), so:

	[These are not so much bugs as niggles!]

1)
[james@bond sox-14.0.0]$ ./configure --prefix=/usr
	[...many lines of output...]
Debugging build................... no
External module support........... no
ALSA driver....................... no
libao driver...................... no
OSS driver........................ yes
SUN audio driver.................. no
play and rec symlinks............. yes
libgsm............................ in-tree
libsndfile formats................ no
Ogg Vorbis format................. no
FLAC format....................... no
ffmpeg formats.................... no
MAD MP3 reader.................... yes
LAME MP3 writer................... yes
AMR-WB format..................... no
AMR-NB format..................... no
LADSPA effects.................... no
Secret Rabbit Code resampling..... no

Configure finished.  Do 'make && make install' to compile and install SoX
-----------------------------------------------
[james@bond sox-14.0.0]$ make
	[...many lines of output...]
creating sox
./sox --help > /dev/null
/home/xxx/sox-14.0.0/src/.libs/lt-sox: error while loading shared 
libraries: libmp3lame.so.0: cannot open shared object file: No such file or 
directory
make[1]: *** [play] Error 127
make[1]: Leaving directory `/home/xxx/sox-14.0.0/src'
make: *** [all-recursive] Error 1

2) I think the above 'problem' is generic for Ogg Vorbis, 
FLAC, ffmpeg, MAD MP3, LAME MP3 (and possible 'everything else') on 'user 
friendly' distributions that by default do not build with development 
libraries / header files.
A warning message rather than a silent configure without all the 
functionality might be in order (i.e. rather than "yes"|"no" have
"yes"|"no"|"see note 1 below" with 
  "Note 1: Whilst the package listed is available on your machine, I cannot
  use it without the header files. Please install these and re-run configure
  if you wish to use this/these packages.
  (The header files are often in the 'development library' package of
  your distribution, e.g. libogg0-devel-4.5.6......rpm)."
Or is that too much spoon-feeding?(!)

3) SoX's default installation is /usr/local/bin/sox
on Mandriva it is already installed at /usr/bin/sox
A naïve upgrade doesn't work (as presumably the latter is higher up the 
search path than the former). A sensible upgrade uses "./configure 
--prefix=/usr" (but not all upgraders are sensible?).
There are pro's and con's ... : but if configure finds a previous SoX in a 
sensible location (e.g. /usr/bin/sox) should it configure itself so 'make 
install' overwrites the existing (distribution normal) location ??

4) Trivia (and possible bloat/overkill)
? make the last line of make's output:
	"Make finished.  As root do 'make install' to install SoX."

I don't want any of this, just hoped it might decrease the height of the 
entry hurdle for some potential users.
	Thanks,
