Well a cleaner and easier solution I hope. , line 95 in /var/www/html/admin/modules/ucp/Ucp.class.php has
$output = exec("icu-config --version"); //v4.2.1
Current libicu has replace icu-config with icuinfo so it fails there, so I create /usr/bin/icu-config
with the of
icuinfo 2>/dev/null|grep '"version"'|sed 's/.*">\(.*\)<.*/\1/g'
and everybody is happy. mine issues
