Porting a tool using open() from Unix to Mac

Hello,

after getting my script running (thanks for your answers), I have another
problem:

The open commands seems to make trouble. The script was ported from a Unix
to Mac and therefore uses the / to separate paths and files. I first run
the script and it created files having the "/" in the filename.

To correct this I wrote a little sub replacing the / with an : and called
it in ever opne like that: 
  open(FILEHANDLE, &rewrite_open_str(">path/file.out"))
This would be similar to
  open(FILEHANDLE, ">path:file.out");

But the open fails. In $! I only get "invalid argument".

Can someone tell me what's wrong here?

Thanks in advance,
Jan
