Mountain Lion rvm install 1.8.7 x11 error

After update to Mountain Lion, I tried install 1.8.7, and I got error. X11 file not found, I installed Xquarkz, but nothing changed. Whats wrong?

Fail to find [tclConfig.sh, tkConfig.sh]
Use MacOS X Frameworks.

Find Tcl/Tk libraries. Make tcltklib.so which is required by Ruby/Tk.

Try to install X11 via http://xquartz.macosforge.org/landing/ set the correct path to the X11 library for the compiler with:

export CPPFLAGS=-I/opt/X11/include

then try to reinstall ruby, passing to the compiler where gcc-4.2 is:

CC=/usr/local/bin/gcc-4.2 rvm reinstall 1.8.7

Without CC I got a lot of segmentation faults.

I managed to do following on OSX 10.8.2 without a problem:

rvm install 1.8.7 --with-gcc=clang --without-tcl --without-tk

If you don't need tcl or tk and are using rbenv, this should work:

brew install https://raw.github.com/Homebrew/homebrew-dupes/master/apple-gcc42.rb

CC=/usr/local/bin/gcc-4.2 CONFIGURE_OPTS="--without-tcl --without-tk" rbenv install 1.8.7-p358

Even after the X11 fix I was getting this compile error.

compiling stubs.c
In file included from stubs.c:16:
/usr/include/tk.h:23:3: error: #error Tk 8.5 must be compiled with tcl.h from Tcl 8.5
make[2]: *** [stubs.o] Error 1
make[1]: *** [ext/tk/all] Error 2
make: *** [build-ext] Error 2

After much head scratching I noticed this line in the make output.

Use ActiveTcl libraries (if available).

Turns out I had ActiveTcl 8.4 installed installed years ago, but it was picking up tk.h from /usr/include which is version 8.5.

I couldn't figure out how to safely uninstall ActiveTcl and the ActiveTcl uninstall instructions weren't correct, but I did install ActiveTcl 8.5 and that worked around the issue. ActiveTcl Download here.

Frustrating. Anyway hope this helps someone else.

Here's my .rvmrc bootstrap file for now, hope it helps:

if (uname -a | grep '12.0.0 Darwin' >/dev/null); then
    CC=/usr/local/bin/gcc-4.2 CPPFLAGS=-I/opt/X11/include rvm --install --create --disable-tcl --disable-tk use ree@gemset_name
else
    rvm --install --create --disable-tcl --disable-tk use ree@gemset_name
fi

if ! which bundle >/dev/null; then
    gem install bundler --pre --no-ri --no-rdoc && bundle install
fi


if ! bundle check >/dev/null; then
    bundle install
fi
