Hi JulioC,
The problem is our makelocalrc only recognizes English spellings and is failing on “instalar”. We should have a fix in 6.2, but in the mean time please set your language ot English (i.e. set LANG=en_US or LANG=C) and rerun the installer.
See: PGI 6.13 on Suse 9.3 - crtbegin.o
Sorry of the inconvenience,
Mat
