Well, this is indeed strange. I get no such error -- there simply seems to
be no explicit form for the indefinite integral.
In[1]:=
{$System, $Version}
Out[1]=
{"Microsoft Windows","Microsoft Windows 3.0 (October 6, 1996)"}
In[2]:=
Integrate[Exp[x]/Log[x],x]
Out[2]=
Integrate[E^x/Log[x], x]
Quoting form The Book,(1.5.3),"this integral simply cannot be done in terms
of standard mathematical functions. As a result, Mathematica just leaves it
undone."
