checking whether IMAP works... no
configure: error: build test failed. Please check the config.log for details.

I think this problem appear more than one times. I cannot build my php with imap successfully from the version of 4.3.4 to now.
I've followed the instruction exactly from http://hk2.php.net/manual/en/ref.imap.php.
I've also looked for solutions for this problem from internet and this bug database, but they seem cannot help.

My configure line:
