strange errors on using PyPlot on a 64bit virtual machine

[pog87]

I got a 64bit debian installed over a virtual machine
when I try to load PyPlot I get the following

julia> using PyPlot
Loading help data...
ERROR: syntax: invalid numeric constant 0.5
in include at boot.jl:238
at /home/pog/.julia/Color/src/Color.jl:211
at /home/pog/.julia/PyPlot/src/colormaps.jl:4
at /home/pog/.julia/PyPlot/src/PyPlot.jl:278

of course I have installed matplotlib.
When I try to use it the 'plot' function is working well, while on the other hand the function 'surf' has not been imported.

I appreciate any suggestion...
