	Hi Rooters,

	I run root 3.00/06 with Linux 2.2.17-14 (RedHat 6.1).
	I have just installed version 3.01/02, just in case. 
	When I try to create a map file , I have got the following error
message, in both cases :

root [0] m = TMapFile::Create("test.map","RECREATE",1000000,"Memory Mapped
File")
Error in <TMapFile::TMapFile>: no memory mapped file capability
available
Error in <TMapFile::TMapFile>: mapped file not in mmalloc format or
already open in RW mode by another process
(class TMapFile*)0x871fc00
root [1]  

	Is there some environmental issues I overlooked when I installed
root on my PC ?
