That is the conversion I need and it matches the data I have.  How do I incorporate
this into PROJ.4?  If I look the /usr/local/proj/esri file, they are formated like

# Anguilla 1957 / British West Indies Grid
<2000> +proj=tmerc +lat_0=0 +lon_0=-62 +k=0.999500 +x_0=400000 +y_0=0 +ellps=clr

which is not the same format as the link Oscar provided.
