Gallery install problems



I cannot get my gallery to install. When I load up the install page, it gives me errors that my sessions cannot be opened. I used the one step install

this is the error i get
Warning: session_start(): open(/tmp/sess_c6ffa33d5307a31f8da725460f42455c, O_RDWR) failed: Permission denied (13) in /home/.herminie/abcdang/ on line 110
