I'm using paths like this (on winxp):

DSASPATH = "c:/a_C/dsas/server/"

package.path  = 
DSASPATH.."?;"..DSASPATH.."?.lua;"..DSASPATH.."/apps/?;"..DSASPATH.."/apps/?.lua"
package.cpath = 
DSASPATH.."?;"..DSASPATH.."?.dll;"..DSASPATH.."/apps/?;"..DSASPATH.."/apps/?.dll"

require("testapp")         -- API testing
...
