R-beta: POSIX regular expressions not available !?

When trying grep(), I get the following:

> grep("[a-z]", letters)
Error in grep(pattern, x, ignore.case, extended, value) : POSIX regular expressions not available

I can't find any pointer in the installation kit. How can I configure
R to make it "avaliable"?

I run R in an Irix 5.3 system.

Thanks in advance!
