Error on module install with D 6.4

Hi,

Just tried to install the masquerade module on a D6.4 site running php 5 and I have the following error:

Parse error: syntax error, unexpected T_OBJECT_OPERATOR in . . . /sites/all/modules/masquerade/masquerade.module on line 249

Any ideas please?

I love the idea of this module, very useful indeed. I'll be a happy bunny if I can get this to work!

Thanks ever so much for all your hard work

Biggy
