I installed Pear at one computer locally with the help of this sitepoint article http://www.sitepoint.com/article/get...ed-with-pear/2. then i wanted to use it on other computer and i just copied the file. but it din't work and i had to install it again to use it on other computer (and i am still struggling to use it).

Do i always have to do this to use Pear. if i get a host that won't allow me to use shell then what. can somebody please help me with this concern.
