问题
I installed and run lein, but it seems to slow on My Mac (10.6.4).
Running 'time lein help' gives me
real 11m8.674s user 0m54.297s sys 1m32.621s
I tried once more.
real 15m25.560s user 1m36.087s sys 2m52.745s
What's wrong with this? Is anyone experiencing similar problem? Is there anyway to check what's the problem?

When I install, I used 'sudo lein deps', as I got some errors using 'lein deps'. I guess it caused some problem accessing files. When I run 'sudo lein SOMETHING', it works as usual.
回答1:
It's because of how it looks for hooks. It's explained here: http://groups.google.com/group/clojure/browse_thread/thread/e04ab3f6e17f85c4.
You could give cake a try. It worked out of the box for my simple project.clj without any changes, and is blazing fast because of the persistent JVM it uses.
回答2:
One thing to note is that it will put the src directory on the classpath. If you run it from $HOME and have a 54GB ~/src directory like I do, the JVM will slow to a crawl just trying to find the basic things.

Found solution
sudo lein uses different CLASSPATH than that with just lein. I guess my CLASSPATH that contains clojure or clojure-contrib conflicted with the lein.
When I added this code at line 126 of lein, the problem is gone.
CLASSPATH="/Users/smcho/.m2/repository/leiningen/leiningen/1.2.0/leiningen-1.2.0-standalone.jar:lib/dev/swank-clojure-1.2.1.jar::src/:"
For uninstalling/installing, I asked and got an answer here.
