Sage on Mac OS X Latex Error

[Michael Frey]

I am trying to generate a plot in sage with matplotlib.  When I execute a safefig I get an error:

RuntimeError: LaTeX was not able to process the following string:
'lp'
Here is the full report generated by LaTeX:

Hopefully there is an easy fix for this.  The code works on Centos.

Code:

def shape_plot(rf_shape_pl, amp_shape_pl, phase_shape_pl, Pname_sh):

    """

    Plot Pulse Shape

    x_line= srange(0, 1, 1/len(rf_shape_pl))

    sh_r=ceil(max(rf_shape_pl))

    if sh_r < abs(floor(min(rf_shape_pl))): sh_r = abs(floor(min(rf_shape_pl)))

    fig = Figure(figsize=(8,3))

    fig.subplots_adjust(bottom=0.18, top=0.88, left=0.06, right= 0.97, wspace=0.3, hspace=0.35)

    ax = fig.add_subplot(131)
