Trying to get pg gem installed on Snow Leopard with Postgres's install of
Postgres 8.4 in /Library/PostgreSQL/8.4. I can find a million references to
this problem online, but every one of them has a few "I got it working"s which
don't work for me, followed by folks saying "well, it doesn't for me" and
reproducing what I have below and then no solution.
This is what I'm doing
$export PATH=/Library/PostgreSQL/8.4/bin:${PATH}
$export ARCHFLAGS='-arch x86_64' #I've also tried '-arch i386'
$sudo gem install pg -- -with-pgsql-include=/Library/PostgreSQL/8.4/include/
-with-pgsql-lib=/Library/PostgreSQL/8.4/lib/
Building native extensions. This could take a while...
