Linux Sys Admin Urgently Needed

We have an issue with PHP on one of our colo servers which runs Plesk.

The server is running CentOS5 and we recently ran a yum install php-soap due to requirements of a client site. This has however lead to various errors on the server and has rendered curl unusable. The knock on effect to this means some of our client sites do not function correctly.

The first error :

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/soap.so' - /usr/lib64/php/modules/soap.so: undefined symbol: zend_unmangle_property_name_ex in Unknown on line 0

soap was then "yum removed".

Now we have

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/curl.so' - /usr/lib64/php/modules/curl.so: undefined symbol: interval_g in Unknown on line 0

we need the following resolved by an expert like yourself :

curl to be re-instated and operational
php-soap installed and operational

There are also other jobs that we are looking for in the near future like site replication and warm server standby systems that need to be setup.
