If this is the case, there should be some way for the user to know why they
can't install a package, or a package installation fails. Perhaps 'sage
-optional' should like more than just whether a package is installed or not,
but
the reason it is is not installed.
* It could be like valgrind, where the upstream code simply has not been
written
for Solaris.
* A dependency is not installed.
* A dependency is not GPL2v+.
* An installation failed.
Anyway, it looks like a couple of the Solaris issues are likely just GNUisms.
The '-v' option to 'cp' used in the package
'database_cremona_ellcurve-20071019'
is not very important. According to the 'cp' man page on linux is just:
-v, --verbose
explain what is being done
Dropping that should be fairly harmless, and allow the
'database_cremona_ellcurve-20071019' to build on Solaris.
