problem trying to build maxima-5.21.1

I'm trying to build maxima-5.21.1 from source with an RPM spec which I 
can provide if necessary.

After unpacking to the "BUILD" directory, I have the "maxima-5.21.1" 
source tree and within that, there is "doc/info/figures" where there are 
three files: contour1.gif, contour2.gif, & contour3.gif that have no 
associated .pdf files of the same name as do all of the other .gif files 
in that directory.

I found in "BUILD/maxima-5.21.1/doc/info/Plotting.texi" where the three 
files are referenced, but I'm not familiar enough with .texi files to 
know if they are looking for .gif, or .pdf.

When I do a test compile of the source tree, I get (sorry for all of the 
output, but I didn't
know what might be useful to you):

!pdfTeX error: pdfetex (file figures/contour1.pdf): cannot find image file
  ==> Fatal error occurred, no output PDF file produced!
/usr/bin/texi2dvi: pdfetex exited with bad status, quitting.


My questions are:
Is it an oversight that the three contour#.gif files have no associated 
.pdf files?
Should I have something installed that produces the .pdf files from the 
.gif files?
What versions of tetex and texinfo are required to produce a useable 
application?
I have tetex-3.0-19 and texinfo-4.13-1.

Thank you for any light you can shed on my problem,
