Виноват-с.

Да вот что-то читал-читал сегодня UpStream/AsNeeded,
втыкал-втыкал в лог, и окромя того, что наблюдается
недолинкованный .libs/libyacas.so, а с самой строчкой
всё в порядке -- ничего не заметил.

Об этой же проблеме Дима тогда же прошлым мартом здесь и говорил
(~s linking).

%description
Yacas (Yet Another Computer Algebra System) is a small and highly flexible
computer algebra language. The syntax uses a infix-operator grammar parser.
The distribution contains a small library of mathematical functions, but its
real strength is in the language in which you can easily write your own
symbolic manipulation algorithms. It supports arbitrary precision arithmetic.
