Sage 3.2.3 on Solaris x86 build notes

Build Issues

• numpy's root finding code segfaults when linked against ATLAS - no solution yet, but as a workaround build numpy without ATLAS support
• spkg-install in jmol is borken - a fix is coming
• gnucrypot 1.4.0 needs too much entropy at startup - an upgrade to 1.4.3 fixes that. From the release notes of version 1.4.1 (2008-04-25):

* Fixed a bug introduced by 1.3.1 which led to the comsumption of far 
too much entropy for the intial seeding.

Fixes

• sage-native-execute is using bashism:

• Singular seems to be limited to about 180 characters via the pexpect interface. Applying this patch works around that limitation by using the file interface:

• Other fixes to the Sage library: 3.2.3.final-solaris-fixes.patch, 3.2.3.final-solaris-getrusage-.patch

Doctest Failures

• coming soon - about 30 doctests failed, but about 15 to 20 are fixable with little effort

Other Annoyances

• -sdist as well as -bdist is seriously broken with BSD-ish shell utils installed in the default path on Solaris
