Did you compile with exactly same configure line? (nothing has changed in PHP that could have broken this..)

Yes, that is 100% - I've double checked that.
Completely same ./config options
They can't be mistyped because I've copy pasted it from text file.
All works with 5.2.1, but all same enviroment fail with 5.2.2

Are you sure that your c-client is built with SSL support?

The error you are seeing would happen if this wasn't the case.

No I don't guarante that c-client is built with SSL support.
I haven't compiled it myself, bit added it like a freebsd port"
pkg_add -r port_name.

I also disagree, because, It wouldn't work then with current 5.2.1

They share same config so error would appear in 5.2.1 as well as in 5.2.2

PS: In 5.2.1 I used IMAP without --with-imap-ssl=/usr/local/openssl
option so it worked without IMAP ssl. Exactly same I wana apply to 5.2.2.
That is without --with-imap-ssl=/usr/local/openssl in .config

This time I've reached for a last resort option and that is completely DELETING php folder

Then:

tar -xvf php-5.2.2.tar (NOT re-downloaded again)
./configure - copy-paste it like before (imap without SSL)
make
make test
make install

Then I deleted "new" php.ini and restored one "old" one that 5.2.1 used and voila!

It started to work

PS: This are my failed tests:
