Many major ports won't compile since upgrading to Snow Leopard

[macports_nospam@…]

I've been struggling to follow the instructions in the Migration page for a couple of days. I've used Macports extensively under 10.5.x without any problems (for Ruby on Rails development). I tried searching the wiki for help, but there were over 500 entries for apache2 alone, all way over my head.

1. I upgraded my iMac from Leopard to Snow Leopard 10.6.1. I downloaded and installed the latest XCode.

2. I downloaded/installed the Snow Leopard version of Macports, then Cleaned All and Uninstalled all my ports.

3. Ruby, Ruby91, Mysql5, lynx, AquaLess, and git-core installed without difficulty.

4. Trying most other installs generates errors that prevents any success. Generally one of the dependencies gets screwed up, although I'm not enough of a programmer to understand the error messages.

5. Failed installs include:

a) apache2 ("could not find Cyrus SASL v2", even though I've installed it several times with multiple variants); b) subversion (can't decipher the error); c) ImageMagick (chokes at xorg-libXt); d) rb-fcgi (chokes on help2man)

6. Sometimes I've been able to overcome an "wrong architecture" message by installing a dependency with the +universal option set. Uninstalling, cleaning, then installing above files with +universal didn't help.
