I get similar error messages when attempting a fresh install of SS 2.3.7 and 2.4 in Snow Leopard (Cannot modify header information). Managed many installs (with Leopard) before. De-zipped packages with "The Uninstaller". Ran permissions.
This error is when installing 2.4. Previous SS installs work fine locally.
