1. You don`t have to compile it.
2. Go to
http://www.tcl.tk/software/plugin/ and download the
XPI (I used Linux XPI 32-bit). Unzip it (if any problems rename it to .zip - it's just a zip file) to a directory.
3. move all but the install.js into your browser's plugins directory -
/usr/lib/mozilla/plugins/, this means
libnptcl3.1.so and
nptcl directory (from uzipped files) - root access needed.
If you want to install for a current user only use:
/home/your_dir/.mozilla/firefox/something1234.default/plugins/ . If you don`t have the "plugins" directory just create it.
4. Restart browser and go to
http://www.tcl.tk/software/plugin/applets.html and choose "dragable text" applet. It should work - for me most of them do.
If it helps mark the thread as [solved].
Good luck
