You could try going into the tp/Texinfo/Convert/XSParagraph subdirectory
and running

TEXINFO_XS=debug ${PERL} -I ../../../ -I . fail.pl

where ${PERL} is the path to your Perl executable. This should give
an idea what point it is failing at. For example, I get the output

checking ../../..//TestXS.la
checking ./TestXS.la
found ./TestXS.la
./.libs/TestXS.so loaded
looking for boot_TestXS
trying to call boot_TestXS...
  ...succeeded
message from XS module

which shows it loaded successfully.
