Whenever I try something with symbolic manipulation in Sage, ECL throws an
error:
var('x')
simplify(x^3)
Internal or unrecoverable error in:
Got signal before environment was installed on our thread

I'm running Sage 6.6
version()
'SageMath Version 6.6, Release Date: 2015-04-14'
on Gentoo Linux using the sage-on-gentoo overlay.
uname -a
Linux t-rex 3.17.7-gentoo #1 SMP Mon Dec 22 12:30:30 CET 2014 x86_64
Intel(R) Core(TM) i5-4200U CPU @ 1.60GHz GenuineIntel GNU/Linux
I tried reinstalling every related package (sage, maxima, ecls) several
times, removing and reenabling threads support, even remerging my whole
system, without success. Recently I created a sandbox and installed
everything from scratch there - same error.
Symbolic computation in Maxima itself is just fine, though.
Does anyone have an idea what could cause this problem? Or what is even
meant by the error? What file or directory isn't found? Thanks in advance.
