New description:
Cygchecking the package shows that it looks for an inexistent
libLfunction.so.
Indeed, this file is moved to libLfunction.dll on Cygwin to let Sage
build.
But at runtime, it is the original .so file which is looked for (surely
some DT_SONAME equivalent).
Letting libLfunction.so in place and symlinking it from libLfunction.dll
seems more functional.
A better solution would to tell lcalc to build directly a .dll file on
Cygwin (and .dylib on Mac OS X, etc.).
Updated spkg doing so at
