This still doesn't belong on cygwin-apps. ;-)

Now for your real troubles.  Did you compare the two cygcheck outputs
yourself at all?  In short, apart from answering "what's different on your
two machines?", your two cygcheck outputs lead to asking "what's *not*

- You have *completely* different versions of Cygwin and most of the
  packages at work and at home.

- You have different environment settings, in particular PATH, on the two

- You have *four* cygwin*.dll's at home (NT machine):
  * the 1.3.20 cygwin1.dll in f:\cygwin\bin;
  * a cygwin.dll from 1996 in d:\bin;
  * and both a cygwin1.dll and a cygwinb19.dll in d:\4TEX5.0\BIN\WIN32.

Aside from that,

1) probably arises from you having a later version of base_files on your
   work machine.  You very likely had either .bash_profile linked to
   .bashrc on your home machine, or had a custom .bash_profile that called
   .bashrc.  Either that, or you don't pass a --login flag to bash at

2) most likely is the same problem that other people were having with
   PERLIO in perl 5.8.0 (your home machine has 5.6.1).  Try setting
   PERLIO=perlio in the environment (see

3) I have no idea about.  Since you have the same version of mutt on
   both machines, I'd guess it's a permission problem.
   Are your mailboxes on a local drive, or a network one?  What's the
   output of "ls -l" and "ls -ln" on all of your mailboxes on both
   machines?  Are your /etc/passwd and /etc/group up to date on both
   machines?  You have a capitalized "P" in the username on your work
   machine, and the UID is >10000, which means you're a domain user.  Did
   you ever wonder what group name "mkgroup_l_d" means?  Looks like your
   Cygwin is on NTFS in both cases, though, so that's not an issue.

By looking into the above you're likely to fix most of your problems.
If this doesn't work, your suggested course of action is the following:

- Back up your home directory on your work machine (mv /home /home-old).
- Transfer over your home directory from home (tar -cjf
  /cygdrive/c/my_home.tar.bz2 /home) to your work machine (tar -xjf
- Also transfer the local setup cache (f:\cygwin\downloads) to your work
  machine (you can simply copy it to c:\cygwin\packages there).
- Run setup.exe, select "Install from Local Directory", then choose all
  the needed packages.  This will downgrade most of the packages on your
  work machine, and bring it in sync with your home machine.
- Try out your programs, make sure they work.
- Then (and only then) upgrade packages one by one from the net to see
  which one breaks things; if it does, downgrade it or ask how to fix
  things on this list - it'll be easier to help with one package
  misbehaving all other things being equal.

This way you first get an installation on your work machine working the
way you want it, and then you can make it the latest and greatest.

Hope this helps,
