Replying to myself here, but after reading the link you provided I think
I understand what the author means. Specifically:
============= Quote
Licensing and ordering
Libpropc++ has dual licensing:
LGPL 2.1
You are allowed to use libpropc++ only for open source software
(because of LGPL issues related with templates).
Commercial License
Can be used to develop commercial applications.
Order/download libpropc++ at http://ex-code.com/propcpp/.
============= End Quote
Since template code cannot be 'separated' from the rest of a program
into a shared library, all the files that depend on a template library
(such as, in fact, libsigc++) will have to be open-sourced in order to
comply with the terms of the LGPL. This does indeed implicate that you'd
have to open-source at least a part of your program in order to be able
to use libsigc++.

Libsigc++ and gtkmm are released under the LGPL which you can find on
http://www.gnu.org/licenses/licenses.html#LGPL.
In short, it comes down to the following: you can use gtkmm/libsigc++ in
code for which you provide no source if you give the users of the code
the opportunity to change the part that is LGPL (ie, gtkmm/libsigc++).
You can do this for example by using gtkmm/libsigc++ as shared libraries
(.so on Unix, .dll on Windows) or by providing object code to your
program so that users can re-link with modified versions of the LGPL code.
