[Haskell-cafe] Guidance on symbol error

Hi list. I'm trying to build gruff on Debian Jessie with GHC 7.6.3. I'm
building gruff-0.3.3 because gruff-0.3.4 dependencies seem to be too new
for Jessie. I was able to build all the dependencies of gruff-0.3.3
(after installing a ton of -dev packages). But when cabal tries to build
the gruff package itself, I get this error:

/usr/bin/ld: dist/build/gruff/gruff-tmp/src/compute.o: undefined
reference to symbol '_ZdaPv@@GLIBCXX_3.4'
//usr/lib/x86_64-linux-gnu/libstdc++.so.6: error adding symbols: DSO
missing from command line

It's been quite a while since I did any C++ programming... could
somebody clarify for me what this means? Thank you.
