Subject: Installing tk interface to ruby on RH9.0 GNU/LINUX

Hello,
	I installed ruby 1.8.1 and it works fine. I also installed tk8.4 and
tcl8.4 in /usr/local/ and they work fine too. However when I try to
install the ruby extensions I get errors.

/usr/local/lib/ruby/site_ruby/1.8/i686-linux/tcltklib.so: libtk8.4.so:
cannot open shared object file: No such file or directory -
/usr/local/lib/ruby/site_ruby/1.8/i686-linux/tcltklib.so (LoadError)
        from /usr/local/lib/ruby/site_ruby/1.8/tk.rb:7
        from demo/lines1.rb:3:in `require'
        from demo/lines1.rb:3

	Could you suggest what's wrong. The detailed command sequence for
installation is given in the end of this mail.

Thank You,
Himanshu.

P.S.
	I start with extconf.rb as follows:-

[root@Himanshu-tcltklib]#CONFIGURE_ARGS='--with-tcl-include=/usr/local/include/ --with-tk-include=/usr/local/include --with-tcl-lib=/usr/local/lib/  --with-tk-lib=/usr/local/lib/ --enable-tcltk_stubs --with-tcllib=tcl8.4 --with-tklib=tk8.4' ruby extconf.rb
