string-match error

Hello y'all,

I am having problems using string-match. I have created a small script

that calls string-match and I get:

/home/ariel/console/mce/tests/./panda.scm:4:9: In procedure module-lookup: Unbound variable: string-match

If I start guile and then use string-match there is no problem:

scheme@(guile-user)> (string-match "a" "a")

$1 = #("a" (0 . 1))

It also works if I start guile and then load the file:

address@hidden tests]$ guile

GNU Guile 2.0.9

Guile comes with ABSOLUTELY NO WARRANTY; for details type `,show w'.

This program is free software, and you are welcome to redistribute it

under certain conditions; type `,show c' for details.

Enter `,help' for help.

scheme@(guile-user)> (load "panda.scm")

#(a (0 . 1))

The file contains:

#!/usr/local/bin/guile \

-e main -s

(display (string-match "a" "a"))

Is there something that I am missing?

thanks,

ariel
