Hi again,

Thank you Jack and Antoine for your suggestions. Still running into trouble....

I tried this manner of installing pd 46.6 again:

$ sudo apt-get update

seemed to work fine.

when running:

sudo apt-get build-dep puredata

I get:

reading... done

buidling depend... done

reading state.... done

E: You must put some 'source' URIs in your sources.list

then when I try to run:

$ autogen.sh

I get:

autoreconf: (12 of these)

then

configure.in.:104: error: possibly undefined macro: ACLIBTOOL_WIN32_DLL

If this token and others are legitimate, please use m4_pattern_allow.

See the Autoconf documentation

configure.in:105: error: possibly undefined macro: AC_PROG_LIBTOOL

autoreconf: /usr/bin/autoconf failed with exit status: 1

Yes, now you need libtool.
Try something like :
$ sudo apt-get update
$ sudo apt-get build-dep puredata
and try to re-compile.
Or you can follow instructions given by Antoine.
