bioperl

问题 I am trying to install a perl module Bio::DB::Sam on my home directory on a remote server. I downloaded the module, extracted the files, and ran: perl Build.pl prefix=~/local this is what happens next: This module requires samtools 0.1.10 or higher (samtools.sourceforge.net). Please enter the location of the bam.h and compiled libbam.a files: **/some_places/samtools-0.1.19** Found /some_places/samtools-0.1.19/bam.h and /some_places/samtools-0.1.19/libbam.a. Created MYMETA.yml and MYMETA.json
