Okay, valuable things when learning ruby:

• ri – This is like “perldoc”. Use it to view the live ruby documentation.
• irb – Interactive Ruby. This is like the perl debugger.
• IRB Tab Completion—Use this to view every available method on every object.
• gems – A packaging system and source code repository (kinda like CPAN)

• RubyGems

If you get this CUPS error, it may mean that you don’t have write permission to your CUPS spool directory (/var/spool/cups, by default).

Here’s the build flags I used for building a 64-bit GCC for Solaris 9 (using Sun’s Forte C compiler). This uses the GNU binutils ld and as.

export GCC_EXEC_PREFIX=
export LD_LIBRARY_PATH=

 cd build;
        test -d gcc-4.0.2 || gtar -jxvf ../src/gcc-4.0.2.tar.bz2
        test -d objdir && rm -rf objdir 
        mkdir objdir
        cd objdir
                CC="cc -xarch=v9" ../gcc-4.0.2/configure  
                        --prefix=/apps/gcc/4.0.2 
                        --enable-languages=c,c++ 
                        --with-ld=/apps/binutils/stable/bin/ld 
                        --with-as=/apps/binutils/stable//bin/as 
                        --enable-threads=posix 
                        --disable-shared 
                        --enable-multilib
                while ! gmake -j16 bootstrap MAKE=gmake BOOT_CFLAGS="-g -O2 -m64"; do
                        true;
                done

Since this isn’t documented anywhere in the ruby install docs that I can find… If you want your Ruby build to have openssl support, you’ll need to compile with—with-openssl-dir=, pointing at your OpenSSL build.

It seems kind of basic, but it doesn’t show up in a ./configure—help, and it’s not anywhere in the docs that I can find.
