Dear Emanuel,
Let us explore the possibility that we have a dependency issue.
1) Please let me see the output of
$ ./wp-mirror-0.2.lisp --debug
It should be:
;debug: Processing command line arguments ...
2) Debian Sqeeze uses clisp 2.48. I think Ubuntu Lucid uses clisp 2.44. Please let me see the output of:
$ clisp --version
The first line of mine reads:
GNU CLISP 2.48 (2009-07-28) (built 3487543663) (memory 3506736573)
3) WP-MIRROR make use of functions such as `ext:probe-pathname' and `posix:file-size' which were first introduced in clisp 2.47.
Please let me see the output of:
$ clisp -q [1]> (ext:probe-pathname "/etc/hosts")
Mine reads:
#P"/etc/hosts" ; #P"/etc/hosts" ; 3533434716 ; 2321751
Sincerely Yours, Kent
