Exist() doesn't understand wildcards, but Dir() does, but not with the
same syntax as the shell, but with Gambas's LIKE syntax. You can use

  If Dir("/srv/gbshared/lib", "ph.internals:*.gambas", gb.File).Count > 0 Then
  ...

This does not short-circuit to returning True as soon as a file matching
the pattern is found, but always gives you the entire array of all matches
before you call Count on it, but probably that's not a critical overhead.

Tobias
