[GAP Forum] Problem installing GAP 4.5 using BOB

[Sandeep Murthy]

Hi,

I am unable to install GAP 4.5 using BOB.

I think I followed all the instructions on this page:

http://www.cs.st-andrews.ac.uk/~neunhoef/Computer/Software/Gap/bob.html#installprereq
.

Firstly, I am running Mac OS X 10.8.2 on a new system, which did not have
Xcode.  So I started by installing XCode, and then installing MacPorts.
 After
this I downloaded bob-osx.dmg, and then ran that.  I then ran the 'bob'
script,
but I got the following output:

--------------------------------------------------------------------------------------------------------------------------------------------------

sudo port install readline +universal ncurses +universal gawk wget
xorg-libX11 xorg-libXaw

I don't know what the problem here is.  Firstly, it is saying that Xcode is
lacking some components,
but it is up to date.  Could it be a problem with file permissions?  I have
turned-on FileVault (the file
encryption system), and firewall, and have selected a security option which
only allows those applications
to be run which have been downloaded from the Mac App store or from
"identified developers".

Any help or suggestions as to how to proceed would be greatly appreciated.

Sincerely, Sandeep.
