It should be set to $SAGE_LOCAL/share/terminfo

Don't claim this is a bug, but don't understand this.
Define {x} the fractional part of x by (source mathworld):
def fra1(x):
fractional part
return 1/2+I/(2*pi)*log(-exp(-2*pi*I*x))
sage: var('x')
x
sage: ii=integrate(fra1(1/x),x,1/2,1);ii
log(2)
According
Dear list,
Setup : sage 5.11 on Debian amd64 self-compiled (Debian's compilers and
tuned Atlas library)
trying to put on paper the elementary proof that the convolution of two
normals is a normal, I stumbled on what I think to be a disastrous bug.
What follows is shown in text mode, but
Well, the derivative of the fractional part is indeed 1 where it is
defined, as
lim((fra(x+eps)-fra(x))/eps)=lim(eps/eps)=1 unless adding eps crosses a
boundary,
which it won't do for eps small enough.
Maxima (5.29) returns (4 pi log 2 + i log(-1) +pi)/(4 pi).
Depending on the value of log(-1),
