The issue appears to be with the use of subdirectories with @include and
specifically relative file names beginning "../".
I tested with texi2pdf --clean for an include file in a subdirectory, like -
@include subdir/thefile.texi
- but this worked fine. However, when it looks like -
@include ../include.texi
- this breaks. Running
KPATHSEA_DEBUG=32 texi2pdf --clean main.texi |& tee log
shows the following:

The relevant documentation is in the "kpathsea" Info manual:
>>>
Each path element is checked in turn: first the database, then the
disk. If a match is found, the search stops and the result is returned.
This avoids possibly-expensive processing of path specifications that
are never needed on a particular run. (Unless the search explicitly
requested all matches.)
Although the simplest and most common path element is a directory
name, Kpathsea supports additional features in search paths: layered
default values, environment variable names, config file values, users'
home directories, and recursive subdirectory searching. Thus, we say
that Kpathsea "expands" a path element, meaning transforming all the
magic specifications into the basic directory name or names. This
process is described in the sections below. It happens in the same
order as the sections.
Exception to all of the above: If the filename being searched for is
absolute or explicitly relative, i.e., starts with '/' or './' or '../',
Kpathsea simply checks if that file exists.
>>>
Under texi2pdf --clean, processing takes place in a different subdirectory
to the input file. Hence a route to the file beginning ".." based at the
location of the input file will be incorrect. I cannot see any hope of
making this work, either in Texinfo or kpathsea.
Therefore, I recommend you avoid the use of file names beginning "../"
with @include commands. There are a couple of ways you could do this:
* Restructure your project to put include files in lower-level directories
* If that is not possible, you could use the TEXINPUTS variable. Replace
@include ../mastaba/ramasutra.texi
with
@include mastaba/ramasutra.texi
and then when you are running texi2pdf, you have to make sure that the
directory containing the "mastaba" directory is found via TEXINPUTS. See
the "kpathsea" manual for more information.
