I'm not aware of such a utility, but I've never looked for one.

In reading the lame man page, there's a special switch for "gapless
encoding" which makes me think that the default mode is to include gaps
for contiguous files.  If that's the case, you can simply experiment with
dumping giving lame a string of raw PCM or PCM with WAV file headers and
letting it handle the gaps.

I also might just do something LIKE this:

for song in *.mp3; do
	mpg123 -s $song >>longsong.raw
	mpg123 -s blank.mp3 >> longsong.raw
done
# Of course, this adds some blank to the END of the album, but you can
# figure out your way around that.
lame -m s -r -s 44.1 longsong.raw album.mp3

But those are just some suggestions.  You'll have to play with the
options.
