There's a SlackBuild for aubio-0.3.2, it's for 13.37, so I'm not sure if it would be OK for current. But you could try it.

I tried the slackbuild for 13.37 and i get the same error. I also tried reverting back 0.3.1 and i get the same thing. Googling around, people people are talking about linker issue and stuff i don't really understand.

Press the Report button and ask for this thread to be moved to the Slackware forum, possibly get more help there.

luckily gcc-4.7 is very eloquent

add a line
Code:
LDFLAGS="-lm" \
to the configure block of the slackbuild, like
Code:
LDFLAGS="-lm" \
CFLAGS="$SLKCFLAGS" \
CXXFLAGS="$SLKCFLAGS" \
./configure \
