Right, sorry. `-f' option is available.

I can confirm that using the shebang above and copying browser/ to
/usr/bin/gst-blox works.

It reminds me of a patch (attached) I apply to GNU Smalltalk for Debian
package because the shebang in the image does not work. I was told that
what is behind the shebang is passed as a single argument.

The following snippet illustrate this. On my Debian GNU/Linux box:

  address@hidden cat shebang1
  #! /bin/echo -e
  address@hidden ./shebang1
  address@hidden ./shebang1 whatever
  ./shebang1 whatever
  address@hidden cat shebang2
  #! /bin/echo -e whatever
  address@hidden ./shebang2
  -e whatever ./shebang2

That is, /bin/echo from shebang2 receives '-e whatever' as first argument.
Hence /usr/bin/env receives `gst -aI...' and fails. With the patch,
executing works.

The patch is crude because it hardcodes the path to gst, I guess it could be
modified to use @automake@ variable and work in all cases; but then we'll need
to check if dummy[64] is not exceeded.
