You don t name server type, but Free pascal ( http://www.freepascal.org ) comes with nearly every Linux distribution nowadays, as well in the FreeBSD ports and on Mac OS X (x86+ppc + 64-bit of both, via fink or standalone .dmg installer).
For windows and dos there are normal all-in-one installers at http://www.freepascal.org
If you want more Delphi like RAD editing, you probably want Lazarus ( http://Lazarus.freepascal.org , also available for the above platforms, except for dos)
Solaris x86+sparc exist, but are a bit experimental.
If it is a windows server, Delphi is also possible, but free versions are hard to get (if at all) nowadays.
