This should be provied by the tomlib package, which is I think part of
the Sage optional package "gap_packages-4.6.4.p1" or maybe
"database_gap-4.6.4". If you install those packages, you'll have a
directory local/gap/latest/pkg/tomlib. However, tomlib still doesn't
work:

salvus@compute1dc2:/usr/local/sage/sage-6.2.rc0/local/gap/latest/pkg$ sage -gap

gap> TableOfMarks( CharacterTable( "A5" ) );
fail


I also tried downloading the latest version of tomlib from
http://www.gap-system.org/Packages/tomlib.html and manually placing it
there, and it also doesn't work.

Hopefully a GAP expert can say more.

it is meanwihile 4.7.4. (However, one can just do
"sage -i database_gap" to install the latest one)

indeed! It turns out that nowadays Tomlib depends upon another GAP package, AtlasRep,
which Sage is not providing.

While we deal with fixing this, one can manually install atlasrep into
local/gap/latest/pkg/
which is just unpacking the tar file from
http://www.gap-system.org/Packages/atlasrep.html

After this:
gap> LoadPackage( "tomlib" );
true

gap> TableOfMarks( CharacterTable( "A5" ) );

TableOfMarks( "A5" )
gap> t:=TableOfMarks( CharacterTable( "A5" ) );
TableOfMarks( "A5" )
gap> Display(t);
1: 60
2: 30 2
3: 20 . 2
4: 15 3 . 3
5: 12 . . . 2
6: 10 2 1 . . 1
7: 6 2 . . 1 . 1
8: 5 1 2 1 . . . 1
9: 1 1 1 1 1 1 1 1 1

gap>
-------------------
Note that one needs to load this package explicitly:

gap> LoadPackage("tomplib");
(or in Sage one does gap.load_package("tomlib))

(in order to check that AtlasRep is installed, one can try
gap> LoadPackage( "tomlib" );
and see that it prints
"true"

Note that AtlasRep will be autoloaded by TomLib.
