IIRC, Perl can spell its exported function names in several different ways (eg, with or without the Perl_ prefix). It looks like plperl is expecting a different convention than what the libperl.so file was actually built with. Use ldd on plperl.so to double check which libperl it's trying to link to. Double check that the Perl header files you compiled plperl against came from the same Perl build that produced libperl.so. regards, tom lane
