libboost_regex-plesk.so.1.54.0: cannot open shared object file

[KirillU]

Distributor ID: Debian
Description: Debian GNU/Linux 7.8 (wheezy)
Release: 7.8
Codename: wheezy

After system upgrade from 7.0 there was also update for Plesk via web autoinstaller, wich was completed with errors. After reboot the panel doesn't work (nginx 502) and SW-engine doesn't start. It asks for package libboost_regex-plesk.so.1.54.0

/usr/bin/sw-engine: error while loading shared libraries:
libboost_regex-plesk.so.1.54.0: cannot open shared object file: No such file or directory

currently installed (in /usr/lib) is version 1.49.0 of this package. need help, how can i get this package updated.

Upd: 1.54.0 is found under /usr/lib/x86_64-linux-gnu/libboost-plesk-1.54.0, but how i tell plesk to look there for it?

Upd2:

ln -s /usr/lib/x86_64-linux-gnu/libboost-plesk-1.54.0/libboost_regex-plesk.so.1.54.0 /usr/lib

solves the problem temporary, but i would like to know a correct solution
