'cygport dep' is empty for orpie

[Andrew Schulman <schulman dot andrew at epa dot gov>]

I'm building orpie 1.5.2 with cygport 0.24.0 and ocaml 4.04.0. cygport script is
below.

orpie builds and runs fine. But surprisingly, 'cygport dep' comes back empty:

$ cygport orpie.cygport dep
$ 

even though /usr/bin/orpie depends on libgsl19, libncursesw10, and libblas0:

$ ldd orpie-1.5.2-3.x86_64/inst/usr/bin/orpie
    ntdll.dll => /win/c/WINDOWS/SYSTEM32/ntdll.dll (0x7ffc9bed0000)
    KERNEL32.DLL => /win/c/WINDOWS/System32/KERNEL32.DLL (0x7ffc9a760000)
    KERNELBASE.dll => /win/c/WINDOWS/System32/KERNELBASE.dll (0x7ffc98e70000)
    cygwin1.dll => /usr/bin/cygwin1.dll (0x180040000)
    cygncursesw-10.dll => /usr/bin/cygncursesw-10.dll (0x3ec850000)
    cyggsl-19.dll => /usr/bin/cyggsl-19.dll (0x3f5b20000)
    cygblas-0.dll => /usr/bin/cygblas-0.dll (0x3f3e70000)

Any idea why that might be?
Thanks,
Andrew
