Hi

This is from the setup run after updating to the latest ghostscript
package:

What does this

 path to alternate expected in /var/lib/alternatives/gs

mean ?

I can't even do the following anymore

  > alternatives --display gs
  > path to alternate expected in /var/lib/alternatives/gs

These are the two postinstall sripts for the native and the x11 version of
ghostscript:

------------------------------ ghostscript.sh ---------------------------------
#!/bin/sh
prefix=/usr
bindir=${prefix}/bin
sbindir=${prefix}/sbin

${sbindir}/update-alternatives --install ${bindir}/gs gs ${bindir}/gs-native 10
-------------------------------------------------------------------------------

------------------------------ ghostscript-x11.sh -----------------------------
#!/bin/sh
prefix=/usr
bindir=${prefix}/bin
sbindir=${prefix}/sbin

${sbindir}/update-alternatives --install ${bindir}/gs gs ${bindir}/gs-x11 20
-------------------------------------------------------------------------------

And these are the preremove scripts:

------------------------------ ghostscript.sh ---------------------------------
#!/bin/sh
prefix=/usr
bindir=${prefix}/bin
sbindir=${prefix}/sbin

${sbindir}/update-alternatives --remove gs ${bindir}/gs-native
-------------------------------------------------------------------------------

------------------------------ ghostscript-x11.sh -----------------------------
#!/bin/sh
prefix=/usr
bindir=${prefix}/bin
sbindir=${prefix}/sbin

${sbindir}/update-alternatives --remove gs ${bindir}/gs-x11
-------------------------------------------------------------------------------


When I remove /var/lib/alternatives/gs and start from scratch I get:

12:09 AM [499]> rm /var/lib/alternatives/gs
vzell AT vzell-de /tmp
12:09 AM [500]> update-alternatives --install /usr/bin/gs gs /usr/bin/gs-x11 20
vzell AT vzell-de /tmp
12:10 AM [501]> update-alternatives --display gs                               
path to alternate expected in /var/lib/alternatives/gs
vzell AT vzell-de /tmp
12:10 AM [502]> cat /var/lib/alternatives/gs
auto
/usr/bin/gs

/usr/bin/gs-x11
20
vzell AT vzell-de /tmp
12:11 AM [505]> ls -lt /usr/bin/gs /etc/alternatives/gs /usr/bin/gs-x11*
lrwxrwxrwx 1 vzell admin       15 Apr 15 00:10 /etc/alternatives/gs -> /usr/bin/gs-x11*
lrwxrwxrwx 1 vzell admin       20 Apr 14 09:11 /usr/bin/gs -> /etc/alternatives/gs*
-rwxr-xr-x 1 vzell users 11212800 Apr 13 17:29 /usr/bin/gs-x11.exe*
vzell AT vzell-de /tmp


I also found the following in the archives:

  o http://www.cygwin.com/ml/cygwin/2007-11/msg00304.html

On my machine I get:

alternatives --display unison
path to alternate expected in /var/lib/alternatives/unison

Hmmmmmmmm...

Ciao
  Volker
