[gtkmm] Newbie build problem

[William Trenker <wdtrenker yahoo ca>]

I just downloaded and successfully built and installed libsigc++-1.2.3.  Then I downloaded gtkmm-1.2.10 and I run into this:

./configure
<snip>
checking for sigc-config... no
checking for libsigc++ - version >= 0.8.5... configure: error: Libsigc++ is required to compile Gtk--. If libsigc++ was installed
but no found to be sane,  most likely you have not placed the 
/usr/local/lib path in the library config file and run ldconfig.

This shows up when I do a locate:
/usr/local/lib/libsigc-1.2.so
/usr/local/lib/libsigc-1.2.so.5
/usr/local/lib/libsigc-1.2.so.5.0.3

/usr/local/lib is in my /etc/ld.so.conf file and I did run ldconfig after installing sigc++.

the sigc++ include files are located here: /usr/local/include/sigc++-1.2/sigc++/*.h

I have a Linux 2.4.19 system with gcc 2.95.3 and related build tools.

Thanks for helping,
Bill
