The easiest way is to look at the output of "cygcheck -l <package name>".

Exactly.  Pay especial attention to the bit about attaching the output of
"cygcheck -svr" on your system.

However, this is also most likely not the full error message.  It probably
looks like "bash: line N: [: /cygdrive/c/Documents: binary operator
expected".  At a guess, one of the /etc/profile.d scripts is using an
unquoted variable in a test.  The best way to track this down is to try
running

bash --login -x -c "echo Hi" 2>&1 | less

and searching for "binary operator expected".  The line printed right
before the message is the culprit.  It'll likely look like "++ '[' -d
/cygdrive/c/Program Files/Something ']'".

Then scroll backwards to the line that starts with a '+' (it'll probably
look like "+ . /etc/profile.d/something.sh") and that will be the file
that contains the unquoted variable.

HTH,
