three thoughts come to mind:

1. have you tried just installing the 32-bit .deb package? you would
need to add the i386 architecture (with 'dpkg --add-architecture i386')
if you haven't already done so. you'd also need to install any i386
libraries and other packages depended upon by the 32-bit .deb (you can
apt-get install them once you've added the i386 architecture)

2. check the source for debian build scripts etc. if they are included,
look for the Build-Depends: line of the .../debian/control file and
apt-get install the packages listed. you should then be able to build a
64-bit .deb

3. try a google search for the full filename of the package in
double-quotes and amd64. e.g. '"foo.deb" amd64' - someone may have
already gone to the trouble of compiling a 64-bit version and made it
available somewhere. as usual when considering third-party packages,
use your best judgement as to whether you trust the source of the
binary package because by installing the package (and thus running the
install scripts, if any) you are effectively giving them root access.

unofficial packages by debian developers are likely to be safe.

if you want to examine the package without installing it, you can
extract the contents of a .deb package (including the pre and post
install and rm scripts) into a temporary directory using 'dpkg-deb -x
<filename.deb> <dir>'
