Shell script doesn't think a directory is valid (but it is)

I've successfully built a library I'm using on Ubuntu Linux 8.04 (both x86 and x86-64) and now I'm building it on SuSE Linux 9.1 (x86-64). I set the environment variable required for the make script exactly as I set it on the other Linux computers. When I run the make script, I get an error citing that $DEVDIR, which is the root development directory, is not a valid directory. Here's the pertinent part of the script I'm running:

Code:

#!/bin/sh

if test "$DEVDIR" = "" ; then
  echo "Err: DEVDIR undefined...."
  exit;
fi

if test ! -d $DEVDIR ; then
  echo "invalid development root directory:  $DEVDIR"
  exit;
fi

Running this on Ubuntu won't output any errors, but running it on SuSE will give me this error:
invalid development root directory: $DEVDIR
(In place of $DEVDIR, it's showing the actual path to the directory)

So the terminal sees the environment variable (confirmed this with the "env" command), but it doesn't think the variable describes a valid directory. I cd to that directory, copying the contents of $DEVDIR and it works perfectly fine. I even cd'd to / and followed the path all the way to $DEVDIR. There were alternate paths to that directory using links, but I made sure to use the real path.

Stranger still, I had the same problem when trying to run it from the terminal in Apple OSX 10.5 (PowerPC). I figure I'm missing some sort of configuration. Does anyone know what it is?

Is that the exact error message, "invalid development root directory: $DEVDIR"?

No, sorry for being unclear. It really shows the actual path that is stored in the $DEVDIR variable.

Run script as 'sh -vx scriptname' then post the relevant parts containing variables and tests?

Here's the output of 'sh -vx scriptname' on Ubuntu:

Code:

#!/bin/sh

if test "$TECADDONDEVDIR" = "" ; then
  echo "Err: TECADDONDEVDIR undefined...."
  exit;
fi
+ test /duwamishvm03/steve/Desktop/add-on = 

if test ! -d $TECADDONDEVDIR ; then
  echo "invalid addon development root directory:  $TECADDONDEVDIR"
  exit;
fi
+ test ! -d /duwamishvm03/steve/Desktop/add-on

And here's what it looks like on SuSE:

Code:

#!/bin/sh

if test "$TECADDONDEVDIR" = "" ; then
  echo "Err: TECADDONDEVDIR undefined...."
  exit;
fi
+ test $'/home/users/steve/add-on\r' = ''

if test ! -d $TECADDONDEVDIR ; then
  echo "invalid addon development root directory:  $TECADDONDEVDIR"
  exit;
fi
+ test '!' -d $'/home/users/steve/add-on\r'
' echo 'invalid addon development root directory:  /home/users/steve/add-on
invalid addon development root directory:  /home/users/steve/add-on
+ exit

Whoa, what's that "\r" business? Looks like that linebreak either came from Gedit from Ubuntu, TextEdit from the Mac, or Notepad++ from Windows. None of those showed it, but "vi" did. Thanks for the suggestion, unSpawn, I really appreciate it!
