1.4.14 upgrade gives PHP Parse error in PEAR.php

[yosi]

Trying to upgrade from version 1.4.13 to 1.4.14 using the ./bin/installto.sh script generates the following error:
"PHP Parse error:  syntax error, unexpected 'class' (T_CLASS), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' in /zWork/roundcubemail-1.4.14/vendor/pear/pear-core-minimal/src/PEAR.php on line 222"

Used roundcubemail-1.4.14-complete.tar.gz
All previous upgrade using this method went fine.

System info:
ClearOS release 7.9.1 (Final)
PEAR Version: 1.9.4
PHP Version: 5.4.16

Looks like pear/pear-core-minimal 1.10.13 broke compatibility with php 5.4. You have to bump php to 5.5 or use composer and force older version of pear. Or revert this change https://github.com/pear/pear-core-minimal/commit/aed862e95fd286c53cc546734868dc38ff4b5b1d

I'm running ClearOS 7.9.1 - highest possible version. It's fully based on CentOS 7.9.1. The default PHP version for CentOS 7.9.1 is PHP 5.4.16 (which can't be disabled) but it supports officialy PHP 7.X. ClearOS supports until PHP 7.3. ClearOS has a method to appoint specific PHP installed versions to specific virtual hosts. I managed to appoint PHP 7.3 to Roundcube and just upgraded Roundcube to 1.4.14. The broken compatibility for 1.4.14 and PHP 5.4.16 still exists but my problem is solved
