Subject: Re: rvm / gem install not working (zlib issue) on ubuntu

The solution was buried in the install log: the X11 libraries were not 
found. That was a surprise: this window (chrome ..) is running on the 
machine along with a bunch of other gui apps.. i guess there are 
additional libraries required for development.


Use ActiveTcl libraries (if available).
Search tclConfig.sh and tkConfig.sh...............................
Fail to find [tclConfig.sh, tkConfig.sh]
Use X11 libraries (or use TK_XINCLUDES/TK_XLIBSW information on 
tkConfig.sh).
Warning:: cannot find X11 library. tcltklib will not be compiled 
(tcltklib is disabled on your Ruby. That is, Ruby/Tk will not work). 
Please check configure options. If your Tcl/Tk don't require X11, please 
try --without-X11.
Can't find X11 libraries.
So, can't make tcltklib.so which is required by Ruby/Tk.
