(Again, I am building from 6.2.1). 

If I try to configure cygwin with host = "i386-unknown-mingw32", target =
"i386-unknown-cygwin32" it complains that cross compilation is not
supported. Did you mean I should go through the cross compilation process?

Is there an unofficial binary release for ghc-6.2.1 on cygwin?

All I really need is Readline which is not built into the mingw binary
release. Initially I tried to get the mingw build to work. This failed. The
script 'configure' hangs in the step "checking if your perl works in shell
scripts". 

Has anyone had this problem?

Here was my path in the mingw terminal

$ echo $PATH
.:/usr/local/bin:/mingw/bin:/bin:/c/Program
Files/Ghostgum/gsview:/c/Ghostscript/gs8.14/bin:/c/WINDOWS/system32:/c/WINDO
WS:/c/WINDOWS/System32/Wbem:/c/Program Files/Common Files/Autodesk
Shared/:/c/Program Files/Common Files/Roxio Shared/DLLShared

Cygwin is intalled. This problem occurs when c:/cygwin/bin is in the path or
not.

Here is a snippet of the trace where it hangs, in case that could be of use.
