c - unknown type name 'glp_long' (mac osx python, pyglpk) -

i'm trying install pyglpk-0.3 use cobrapie, python version of matlab cobra toolbox. everytime start installation, following errors: (a part of it)

and here part of mentioned c file:

static pyobject* environment_getblocks_peak(environmentobject *self,                        void *closure) {   int cpeak;   glp_mem_usage(null, &cpeak, null, null);   return pyint_fromlong(cpeak); }  #if glpk_version(4,28) #define glp_long glp_long #else #define glp_long glp_ulong #endif  static pyobject* long2py(glp_long l) {   if ((l.hi==0 && l.lo>=0) || (l.hi==-1 && l.lo<0))     return pyint_fromlong(l.lo);   py_long_long ll = l.hi;   ll <<= 32;   ll |= (unsigned int)l.lo;   return pylong_fromlonglong(ll); }  static pyobject* environment_getbytes(environmentobject *self,void *closure) {   glp_long b;   glp_mem_usage(null, null, &b, null);   return long2py(b); } 

do miss install? use python 2.7.5 |anaconda 1.6.1 (x86_64)| , glpk @4.48_0 (active) osx 10.8.4

for me had downgrade glpk way down 4.39 later versions encounter glp_long issue.
