     Type:  defect       |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.7.1
 Keywords:  x86_64,      |       Port:  curl, libpsl, python39, cmake,
  Snow Leopard           |  libomp
-------------------------+-------------------------------------------------
 Bootstrapping Macports with curl ran into unexpected problem on 10.6.8
 x86_64: the following ports call for each other and fail to install:


 {{{
 Error: The following dependencies were not installed because all of them
 have unmet dependencies (likely due to a dependency cycle): libpsl
 python39 clang-9.0 cmake curl libomp llvm-9.0
 Error: Follow https://guide.macports.org/#project.tickets if you believe
 there is a bug.
 Error: Processing of port curl failed
 }}}

 Calling for install of other port instead of curl results in the same
 error:

 {{{
 svacchanda$ sudo ./port -v install libpsl
 Password:
 --->  Computing dependencies for libpsl.........
 The following dependencies will be installed:
  clang-9.0
  cmake
  curl
  libomp
  libpsl
  llvm-9.0
  python39
 Continue? [Y/n]: n
 }}}


 This was vanilla Macports with zero changes to config or portfiles.
 Installed from source with:

 {{{
 ./configure --prefix=/opt/bootstrap --with-applications-
 dir=/opt/bootstrap/Applications --without-startupitems
 }}}
