This was already discussed several times. Just to name a few
reasons why no:

1. Using dynamically linked libraries implies speed penalty.

2. It is likely to cause problems like DLL hell. Even with small
number of carefully selected dynamic libraries nginx currently use
(e.g. openssl) - there are periodically reported problems.

3. It will require to maintain ABI, not something we currently do.
E.g. right now ngx_http_request_s structure changes depending on:
whether pcre library used, http cache enabled, gzip support
enabled, stub status compiled in. Not even talking about local
patches and changes between versions. So things is much more
complex than "0.8.43 needed".

4. Most of us are happy enough with static linkage. Especially
keeping in mind that binary may be upgraded with zero downtime.
