SSIS package Flat File destination URL

I am having a problem when i run a ssis package on the server.  I have created a package that will extract date using an oldb data source and the flat file destination is on a SharePoint portal.  When I run the package on my local machine everything is bueno....  I noticed that the doc location that i paste into the Flat File destination is 

https://portal.example.com/Form Space/Shared Documents/doc.txt

but then i click the browse button and it takes me to select the path and after i select the actual file the path is 

\\portal.example.com@SSL\DavWWWRoot\Form Space\Shared Documents\doc.txt

when i run the package on my local machine the SharePoint Lib updates no problems, but when i move the package to the server and run the package in VS2008 just the same as on my local machine, the error says

Error 1 Validation error. Data Flow Task: Package: The file name "\\portal.example.com@SSL\DavWWWRoot\Form Space\Shared Documents\doc.txt" specified in the connection was not valid.  

Error 2 Validation error. Data Flow Task: Package: The file name property is not valid. The file name is a device or contains invalid characters.  

Has anyone seen this behavior before?

Thanks in advance
