Regexxer on Slackware 12.1
It seemed easy. You just need: libsigc++ 2, gtkmm 2, libglademm 2.4.0, gconfmm 2.6.1 and PCRE. Some of those I already had, so I only needed libglademm and gconfmm.
The first one installed without problems: single tarball,
$ configure --prefix=/usr
# make install
The other one (gconfmm)... well, it turns out you need gconf for that, I did not have it, so hop to the Gnome website.
Done? No, not yet, gconf requires ORBit2, so let go for that one as well.
Now, after running configure, I started make. Since I have dual-core CPU I used make -j2 but it seems I found some bug in make (!?) since it got stuck for 10+ minutes at one single point of compiling, with both CPU cores at 100%. So, I killed it with Ctrl+C and run just make. That went fine and finished in about 2 minutes.
By some magic, I managed to pick the compatible versions, here they are:
I created Slackware .tgz packages for all this, download is here:
