1 Hi all,

3 I am currently trying to get sage to use a system wide singular.
4 This is provided by sage-core-4.5.1-r1 and sage-4.5.1-r1 which
5 are masked. You have to use the latest version of the singular
6 ebuild with the libsingular use flag. If you don't have a folder
7 /usr/include/singular merge singular again as we added some
8 headers that are needed to compile sage-core this week end.

10 It currently segfault on my machine - you've been warned - but
11 I am working to fix it with Thomas Khale.
12 It is uncertain at the moment if sage-4.5.2 (from upstream) will
13 use this version of singular or not - it was planned for 4.5 then 4.5.1
14 and someone else upstream experience segfaults with it -
15 on Solaris. So upstream move may be delayed again.
16 However we want to get rid of sage-singular ASAP.
