Running test script under current devel Vicare does not work

[dgfitch]

Bit of a newbie here, not familiar with Vicare Scheme, so pardon the stumbling.

If I run cosh according to the install instructions, I get library resolution problems.

If I add the new --more-file-extensions parameter after the modified temp output, I get a different error:

$ vicare --more-file-extensions --r6rs-script myprogram.church.tmp

Unhandled exception:
 Condition components:
   1. &who: import
   2. &message: "cannot find identifier"
   3. &syntax:
       form: open-output-string
       subform: #f

I'm afraid I don't know enough about the Vicare implementation to understand what this means, since I'm not getting a file and line number I assume it's some kind of issue in the library importing. -d adds no helpful information. Vicare seems to run simple programs fine.

Again, apologies if this is something obvious. Thanks for the cool-lookin' library... look forward to experimenting with it.
