[ESS] Symbol's function definition is void: regexp-opt

[John Charles Considine]

I'm having a little trouble getting ESS to work on a windows machine.
Xemacs 21.5.17
ESS 5.2.10
R-2.1.1

The init file is based on John Fox's.

Any ideas?

To ensure normal operation, you should investigate the cause of the error

in your initialization file and remove it.  Use the `-debug-init' option

to XEmacs to enter the debugger when the error occurs and investigate the

exact problem.
