There is no need to do any of the tricks with CRLE as described in the link to darksaslight.com in the original question. In fact, I would try to remove any changes if you have done so. The build technique fixed the RUNPATH inside of the libraries so that it knows to look in the various /opt/csw/lib directories without any LD_LIBRARY_PATH or crle tweaks.
You will need the following OpenCSW packages in addition to the base ruby packages:
The libidn_dev is non-obvious since the installer script "helpfully" hides the output of the test compile commmands that it runs. I found it by reviewing the output of truss and discovered that there was a linker error due to the missing library.
You will need to run the following commands either as root or under sudo. I prefixed all of my commands with sudo.
Install the rack and passenger gems:
/opt/csw/bin/gem install rack
/opt/csw/bin/gem install passenger
Then use this command to start compilation:
PATH=/opt/csw/bin:$PATH /opt/csw/bin/passenger-install-apache2-module --apxs2-path /opt/csw/apache2/sbin/apxs --auto
Once that gets going, you may see an error like this:
In file included from /usr/include/sys/types.h:18:0,
/opt/csw/lib/gcc/sparc-sun-solaris2.10/4.6.2/include-fixed/sys/feature_tests.h:341:2: error: #error "Compiler or options invalid for pre-UNIX 03 X/Open applications and pre-2001 POSIX applications"
Command failed with status (1): [g++ -Iext -Iext/common -Iext/libev -fPIC -...]
You can fix that by editing /opt/csw/lib/ruby/gems/1.8/gems/passenger-3.0.11/lib/phusion_passenger/platform_info/compiler.rb and cleaning out the "-D_XOPEN_SOURCE=500" from one of the flags statements. Like so:
if RUBY_PLATFORM =~ /solaris/
flags << '-pthreads'
#flags << '-D_XOPEN_SOURCE=500 -D_XPG4_2 -D__EXTENSIONS__ -D__SOLARIS__ -D_FILE_OFFSET_BITS=64'
flags << '-D_XPG4_2 -D__EXTENSIONS__ -D__SOLARIS__ -D_FILE_OFFSET_BITS=64'
flags << '-DBOOST_HAS_STDINT_H' unless RUBY_PLATFORM =~ /solaris2.9/
flags << '-D__SOLARIS9__ -DBOOST__STDC_CONSTANT_MACROS_DEFINED' if RUBY_PLATFORM =~ /solaris2.9/
flags << '-mcpu=ultrasparc' if RUBY_PLATFORM =~ /sparc/
This gets you to here:
In file included from ext/common/LoggingAgent/LoggingServer.h:48:0,
ext/common/LoggingAgent/../EventedMessageServer.h: In member function 'void Passenger::EventedMessageClient::writeArrayMessage(const char*, ...)':

ext/common/LoggingAgent/../EventedMessageServer.h:118:41: error: 'alloca' was not declared in this scope
Command failed with status (1): [g++ ext/common/LoggingAgent/Main.cpp -o ag…]
To clear that up, edit /opt/csw/lib/ruby/gems/1.8/gems/passenger-3.0.11/lib/phusion_passenger/platform_info/compiler.rb again, and put a line like:
flags << '-I/usr/include'
after "if RUBY_PLATFORM =~ /solaris/" . This is in the section as the above edit.
Also replace the line
flags << '-DHAS_ALLOCA_H' if has_alloca_h?
flags << '-DHAS_ALLOCA_H_' if has_alloca_h?
Note the additional underscore at the end of ALLOCA_H
