I downloaded ruby-1.9.1-p243 and gunzip/tar’ed it. When doing

./configure -prefix=/usr/bin -enable-pthread; make; make install

(BTW, I should have used /usr as bin dir is implied in the build)

[note: Second time when I did it, I ran the following command to compile ruby in Solaris 10:

./configure --enable-pthread --prefix=/usr --exec-prefix=/usr
make
make install

--enable-pthread is not needed if your tck/tl did not compile with this option.
]

It spits error like “no output file specified”. Looking into the C codesm under lib, I chnaged several lines in mkmf.rb, which solved the problem. The chnaged line as reflected in diff:

/home/ror/ruby-1.9.1-p243# uname -a
SunOS zone100-246 5.11 snv_79a sun4v sparc SUNW,Sun-Fire-T200

Did a sym link to make ruby in PATH again:

ln -s bin/ruby ruby

Now I have the newest ruby on Solaris!
