I failed to install gmp 5.02

[Magnus Dicander]

I have had some problems with gmp (Gnu bignum C-library) so i tried to install a new version. When i followed the install-instructions until the command "make install". It gave the error-message: couldn't create directory "/usr/local/share/info" : access denied.
Whats wrong? Is it
1: Gmp-install shouldn't mess with "/usr/local/share/"-directory? or
2: Gmp-install should be allowed to make new directories there?
If the answer is 2, then how will it be fixed?
2a: Official upgrade or
2b: I'll have to chmod some directories to allow scripts to make new subdirectories .
if 2b, then how do i do it?
