Huge problem installing Postgres ruby 1.9 on Vista

[Damjan Rems]

Werent there times when windows gems were precompiled for Windows.

#######################
gem install ruby-pg

extconf.rb:4:in `<main>': uninitialized constant PLATFORM (NameError)

Ok I have edited extconf.rb and add PLATFORM='mswin'
only to get:

c:/ruby19/lib/ruby/1.9.1/mkmf.rb:362:in `try_do': The complier failed to
generat
e an executable file. (RuntimeError)
You have to install development tools first.

Same goes for postgres gem.

########################
Than I tried to go DBI.
gem install dbi
gem install dbd-pg

Building native extensions. This could take a while...
ERROR: Error installing dbd-pg:
ERROR: Failed to build gem native extension.

c:/ruby19/bin/ruby.exe extconf.rb install dbd-pg --no-rdoc --no-ri
ERROR: can't find pg_config.
HINT: Make sure pg_config is in your PATH
*** extconf.rb failed ***

My postgres server is on Linux. I don't need it to be installed localy.
But I think it would die anyway because I don have c installed.

#########################

Ok do some handwork. Download source files from sourceforge, unzip, go
to directory, run ruby setup.rb.
Suprisingly it did well. Both for dbi and dbd-pg. But when I try to run
I get:

c:/ruby19/lib/ruby/site_ruby/1.9.1/dbi.rb:312:in `rescue in
load_driver': Could
not load driver (undefined local variable or method `e' for DBI:Module)
(DBI::In
terfaceError)
from c:/ruby19/lib/ruby/site_ruby/1.9.1/dbi.rb:236:in
`load_driver'
from c:/ruby19/lib/ruby/site_ruby/1.9.1/dbi.rb:154:in
`_get_full_driver'

from c:/ruby19/lib/ruby/site_ruby/1.9.1/dbi.rb:139:in `connect'
from rubyArchiveTesti.rb:16:in `preveriIzXML_Angry'
from rubyArchiveTesti.rb:124:in `<main>'

##############################
Ok. Delete from site_ruby and copy files from old 1.8 directory.

c:/ruby19/lib/ruby/gems/1.9.1/gems/dbi-0.4.1/lib/dbi.rb:294:in `block in
load_dr
iver': Unable to load driver 'Pg' (underlying error: uninitialized
constant DBI:
BD:g) (DBI::InterfaceError)
from c:/ruby19/lib/ruby/1.9.1/monitor.rb:190:in
`mon_synchronize'
from
c:/ruby19/lib/ruby/gems/1.9.1/gems/dbi-0.4.1/lib/dbi.rb:236:in `loa
d_driver'
from
c:/ruby19/lib/ruby/gems/1.9.1/gems/dbi-0.4.1/lib/dbi.rb:154:in `_ge
t_full_driver'
from
c:/ruby19/lib/ruby/gems/1.9.1/gems/dbi-0.4.1/lib/dbi.rb:139:in `con
nect'
from rubyArchiveTesti.rb:16:in `preveriIzXML_Angry'
from rubyArchiveTesti.rb:124:in `<main>'


Here is where I give up.

Has anybody been able to succesfully install dbi with support for
postgres on ruby 1.9.1 and windows vista (xp).
