I finally seemed to manage installation of the DBD::mysql module (previous posts under my name). But, continuing the protocol (as given in OrthoMCL documentation) and testing:
perl -MDBD::mysql -e 1
I get this error:
Can't find 'boot_DBD__mysql' symbol in /Users/arend/perl5/perlbrew/per
at -e line 0.
Compilation failed in require.
BEGIN failed--compilation aborted.
I browsed many sites, each coming up with different solutions, but they don't work. It seems the program is directed somewhere in the wrong place?
