[R-SIG-Mac] Problem with spatstat package

[Rodrigo De Carreras]

Hi list,

I worked with the package spatstat many times without 
problems, but now when I call for the package the following 
error appears with mgcv: 

require("spatstat")

Loading required package: spatstat
Loading required package: mgcv
Error : .onAttach failed in attachNamespace() for 'mgcv', details:
call: formatDL(nm, txt, indent = max(nchar(nm, "w")) + 3)
error: incorrect values of 'indent' and 'width'
Error: package 'mgcv' could not be loaded

I tried to install mgcv alone using install.packages("mgcv")
but the error persists.

I am working in a Mac Book Pro through Snow Leopard.

Any idea about how to solve it?

Thanks a lot,

Rodrigo
