Bug#746048: lcalc: build-depends on libpari-dev appear too loose

[peter green]

Package: lcalc
Version:1.23-dfsg-2
Severity: minor

When building lcalc on raspbian with libpari-dev 2.5.5-1 I ran into the 
following error.

Lcommandline_elliptic.cc:142:40: error: too many arguments to function 'long int* ellinit(GEN, long int)'
In file included from /usr/include/pari/pari.h:56:0,
                 from ../include/Lcommandline_elliptic.h:35,
                 from Lcommandline_elliptic.cc:23:
/usr/include/pari/paridecl.h:1372:9: note: declared here

Based on the fact this went away after a retry with a newer libpari-dev 
I conclude that this is a case of a build-dependency that is too loose.
