[R] C compile problem on Ubuntu linux

[Frank E Harrell Jr]

Under Ubuntu dapper, after installing packages gcc and g77, under

platform i486-pc-linux-gnu
arch     i486
os       linux-gnu
system   i486, linux-gnu
status
major    2
minor    2.1
year     2005
month    12
day      20

language R

I get an error when trying to update.packages('Hmisc'):
