Package: python-scipy
Version: 0.17.0-1
Severity: important

pymvpa2 package FTBFS on mips atm
due to 
Program received signal SIGILL, Illegal instruction
which if ran under gdb provides following detail:

Program received signal SIGILL, Illegal instruction.
0x75de5d44 in cephes_igam (a=5.3023991505199126e-315, x=5.2998088236266445e-315) at scipy/special/cephes/igam.c:199
199     scipy/special/cephes/igam.c: No such file or directory.

and dissassemble at that point leads to

0x75de5d44 <+228>:   add.d   $f6,$f6,$f10

scipy package itself seems to ignore failing tests ATM so it doesn't
FTBFS itself although leads to similar illegal instruction crashes in 
thus hiding the problem and delivering broken scipy on those platforms
