Recently, I've been upgrading manually compiled Asterisk on my Centos to a version coming from Tucny's Repo.
When starting up the Asterisk, I've noticed the following error:
```
asterisk: symbol lookup error: /lib/libasteriskssl.so.1: undefined symbol: ast_register_file_version
```

The problem came from leftover files from the manual build. Here is how I fixed this:
```
rm -rfv /lib/libasterisk*
rm -rfv /usr/lib/asterisk
rm -rf /etc/asterisk
rm -rf /var/log/asterisk
rm -rf /var/lib/asterisk
rm -rf /var/spool/asterisk
yum remove asterisk
yum install asterisk
```
